I am trying to avoid any possible means to customize
my exhaust. I want simple, single cat stock replacment
3" size. I don't want to the spend the money and time
and travel to get to a custom pipe shop. There's only
like 2 around my 50 mile distance!!! And 1 of them is
a PITA to get on the phone!
I will probably get flowmaster anyways. I am just going to
coat the entire exhaust system with special exhaust paint
coating from Summit. Or I may even go with Hooker or
something like that. I don't want rust to form. But I don't
want to spend $550 on Borla. So, I am still up in arms on
what exhaust I want. I'd better hurry, though. I got less than
6 weeks to start my project.

please dont get flow disaster... so common and so boaring. but its your car and you may do as you like
www.mufflex-performance.com if your gonna spend 550 then go with one of their systems. dont be another guy in your town whos got the flowdisaster series
lol that site uses all stainless steel pipes with their systems. if the link dont work do a google search with "mufflex performance" they now include the new stainless steel tips wit hthe logo on them with their cat backs. very nice pieces i must say!
It does go to an "intro" of Mufflex performance. But then
it goes to a page where it's f'd up. Check it out for yourself!
I may look into Thunderracing.com also. They have Hooker
and Random Tech. systems there. Although not stainless,
but still a good product. SLP is ok too. But, I who knows.
I tried it today, NO problems! Maybe the site was down
for a while for maintenance or something. The 82-92
3.5" system looks cool! Should I get the Flowcrapper
muffler or the Spintech muffler? :lala:
For $472.50 plus shipping ain't that bad for stainless
steel. Although it's only 1 exit tailpipe, I've heard that
those make more power than the common dual exit
like from factory. Should I go with the Mufflex system?
Not too many have that, as far as I know.
I have a 40 series Flowmaster,stock cats with 163K miles,edelbrock TES,and its sounds loud and deep at full throttle,but not too noisy at cruise. Does not have the "tin can" sound that I have heard from some. Not sure why that is,but sounds great to me...

oh, definetly the spintech muffler man. yes the one exit pipe is better for power, thats why i am doing a 1 sided exit. get the spintech, youll be very happy

Yeah, I kinda figured that it was the Spintech muffler!
I was joking before about which to get. ( as if you didn't
know! )
So, I will go with the 3.5" 1 side exit exhaust system.
Not too many have the 3.5" size, Spintech muffler or the
1 side exit tailpipe! The only other brand that makes 1 side
tailpipe is Flowcrapper. For our cars anyways. I also talked
to Mufflex about which exhaust to go with on my motor.
They said the 3.5" is fine. Dual exit is heavier ( no duh, more
piping!) and the Single exit is louder. Also, the single
exit system is like over $100 less too. He also said that
they are aluminzed. Not stainless steel. Only the tailpipe
is stainless. So, I will be spraying on that exhaust coat
stuff that Summitracing sells. I hate rust.
I do like the dual exits on our cars. Makes it look like it's
got real dual exhaust. But, time for something different!
Thanks for your help!
no problem. if your going to spray it with anything, get a quart of por15. that stuff works excellent. they do offer the duel outs, but a single 3.5 out one side is going to be big... i will be doing either that same exaust or 2 moroso spiral packs. im undecided as of right now
my 80 series Flowmaster (3" catback) was louder on my 305 than on my cammed out 355.
Actually I like how nice and quiet/smooth it sounds. Doesnt sound like your typical flowmaster... people yell sleeper at me all the time.
I had true dual Flowtech "raptors" on it, and it sounded like a mopar sorta... I liked it but i wanted to quiet it down some, See I daily drive it and have a 3000 stall converter so coming away from lights at 2000 rpm with a loud exhaust gets annoying... fun but annoying. I will probably shoot back to my other true dual setup 40 series longtubes, but thats really loud. its all a jumble!
Some people prefer the quiet, some the noise. Im beginning to prefer the quiet... its more interesting to rape someone without them even realizing you were stepping on it... makes the car seem faster!
wow i do an 80 series search and what do i get...a huge mix in feelings. I personally like everything ive heard from flowmaster setups and havent really considered a diff setup. Ive been told that flowmaster doesnt really rob you of much power even up to 400+hp. Any different opinions on that? I like the mustang gt sound that comes from their stock flowmaster setup and also like what im hearing from the 80 series. After i throw on my hooker 2055s, high-flow catco, and 80 series cat-back will it be too loud? I like raspy loud growling muscle sound. So flowmaster testimonials please stand up
I got the 3inch catback with 3inch dual exits on my stock 350 TPI L98. I also got the hooker shorty headers with Jet Hot coating, and hooker y pipe that comes with the kit. Stock Cat as far as I know.
At first start up without headers, i wasnt real impressed but deffinately louder at idle than before. When reved it was a loud aggressive raspy sound at 4500rpms, and gurgled/popped as the throttle was let off.
Still without headers, After a month of daily driving the exhaust note changed. I guess is cause of heat warping and carbonation. It became louder/deeper (more bass) at idle and really screamed at 4500-5500 rpms. I love the sound. Raspy mean agressive tone.
Then the headers/y-pipe came..... LOL. Lets say theres a bit of difference . It smoothed out the raspy sound a bit at high rpms, and really deepen the sound at idle and low rpms. The crackle/popping after WOT decreased to almost no pops/gurgling. It sounds great. I have no complaints.
But after hearing SLP loudmouth and true dual chambered exhausts, I wish my flowmaster was louder. I love loud mean agressive sounds. Flowmaster 80s sound different from car to car. I heard them on LS1's and dont like it. On some 305's, it doesnt sound to good either. My flow is loud but not as loud as I want it to be. Just my preference since I am a younger kid and want loud.
I get nothing but complements from my exhaust. Now with 2800 stall, its a blast to go thru neighbor hood at 15 mph up the street at 2500rpms
hmm, interesting to hear from someone that has my setup. Ya i like loud but havent been a fan of slp exhaust notes. They seem more racey and just loud than modern muscle. Sound clips would be nice. I might just stick with flowmaster for now and switch down the road when money and cracked valves, heads, and numerous other things arent a problem. BTW is ther anyone with a new high perf. cam, heads, intake and throttle body on thats also got the 80 series? Id like to see what it sounds like when the engine isnt so stock. Ne who thanks for the testimonial it helped alot
Just to put my 2cents in..
I got flow master for my 79 bird, and as soon as they were installed the sound was defening. There was no rumble, it was more like very deep base. It got me sick sitting in it for about 1min. I loved it, people were rolling their windows up and yelling. It was awsome, however later on they broke in and sound awsome. Mind, they are backed with some turbo exaust with turbo mufflers, so it should be quiet. However, it still has that basey sound, however when I setp on it it sounds like a monster. Now this was on a dual exaust so, take it for what its worth. I think that waiting few days for it to brake in will be a good idea. You will notice the difference, I hope!
Good luck.
I have the 80 series with hi-flow cat and i love the sound. Yea iv heard better but the price was good (Not 400 bux!) and i think its an amazing improvement over stock..thats my two cents...
I know alot of people say go be different. Well for me, I am the only thirdgen in my area with the 80 series so it is cool for me.
I am a fan of being different and will get chambered tubes later on sometime. IT will be louder and more powerful. LOL, thinking spiral pro's but hear those are LOUD. i want to run single 3inch pipe splitting into two like Willie's true duals out back with two of those mufflers. It should tame it down a bit and sound good.
Well I just removed my entire headers/Y-pipe/catback/muffler flowmaster american thunder 80 series exhaust system from my car. it is now collecting dust in my shed... better luck next time i guess.
So how do I know what kind of FLOWMASTER I have on my car? And can anyone do away with those political adds on here? I'm here to talk about thirdgens, not Bush
One thing I would say, though i have never own a V6 camaro or a RS, if your wanting to keep your RS then SAVE SAVE SAVE. Save that money and replace that engine, you shouldnt do anything to that V6 if your wanting to hold onto your RS for years to come. You always want to think of your long term goals, how many CI do you want to have, etc. you could always get an iroc or z28. but its always up to you. Some cheap upgrades might be headers or flowmaster. but its up to you
I love when people say theyre breaking in . Its not breaking in, its rotting out...
I have one on the end of my y-pipe as a temporary solution that turned permanent and its sound hasnt changed a bit over the two years ive had it on there. Since the thing is so damn hot it drives off all the water and it cant rot from the inside out.
I dont know about rotting out cuz it wont rot out in like 4 months. The metal shouldnt "rot out" cuz its made to last for longer time due to better materials. Moisture inside does lead to rusting, but I believe the sound does change due to the following reasons
1) Exhaust carbonation/or particle buildup inside the walls of the case.
2) Heat from exhaust warping the dimensions of the baffles in the case and thus changing the flow/sound frequencies in the case.
3) moisture might have a effect of build up of rust or the deteriorization of the metal but this is probly after long time of exposure.
I have an 80 series on my IROC and a 3 chamber on my VortecZ28 and get nothing but compliments on how they both sound.
I love the 80 series, its just a slight bit louder than stock, but sounds aggressive. perfect for cruising the strip.
Give it about a week and the note will change a bit as carbon builds up within the muffler.
I have a 1989 Camaro RS V8, 305, TBI. And I put a 3" Flowmaster catback with a Magnaflow high flow cat, and 3 1/2" tailpipes. It does sound better then the stock set up, but I was hoping that it would have been much louder. It has been about a month and a half and the sound seems to get weaker. A buddy of mine has a like year camaro with a Borla setup and it sounds weak as well. I was so disappointed with Flowmaster and there exhaust systems.
Thats one thing that I dont like about the flows is that they turn into a hollow rusty can when all the condensation in the muffler rusts out the baffles.

Key words here..."305 TBI...high flow cat...cat-back exhaust...weak sound..." It isn't getting weaker, you're just getting used-to it. You have very little mods, a low compression peanut cammed 305 and you want a deap/loud exhaust without even headers??..... saint happenin'.

We put a Flowmaster Street Thunder with Hooker Super Comp ceramic coated headers on my dad's '69 Z-10 Pace Car. It sounds wicked and we are going to put the same thing on my '87 ROC. My dad works the phones in the parts department at Scoggin-Dickey and this is one of the most popular setups they sell. All I have to say is it kicks A$$. The car is not too loud or quiet, but there is no mistaking when we drive up whose car it is, because everyone in the car club starts drooling.
As for the computer adjusting itself, I wish that were true because none of us would have to worry about burning a chip after we do all the latest mods. BS deluxe.
i just scanned through the posts to see what was being said and its obvious, like it always is, that everybody has their own opinion on flowmasters. look, i got my setup (cat, pipes, muffler, chrome tips, and installation done for 100 BUCKS. did the guy get ripped......yeah, should have kept his receipt,lol. im happy with the sound, my ears dont ring, but they are far beyond anything that was ever stock. and yeah, i think they do get better with time......like wine......or in my case, cheap beer. im happy
That's what I did on my POS 305, and it sounds amazing.. For a while I pressed my luck and ran it with a 2.5" straight pipe out the back, which made that 305 sound like it had balls, but also attracted the attention of 1 too many cops!! I got off with just a warning, as I said I was taking it to an exhaust shop to get the muffler replaced.. I don't get how that is illegal, when you have eardrum tearing harleys putting around with exhausts that are just as loud!
Just got a set of SLP headers, got rid of the 305, and put in a 427. Now this is what am talking about. MSD ignition, and some other few goodies. Still got much more to do. But it finally sounds sick as hell.
I've had 2 different thirdgens with flowasters. The first was my 88 bird that I put a 3" flowmaster and I thought it sounded great at the time but I was also young. Then I bought my 86 iroc and it already had a 2.5 flowchoker on it. I put in a healthy 383 with headman shortys and straight piped the cat but kept the flowmaster. The crappy 2.5 bends and 80 series junk made my power drop off around 3500 rpm and after months of tuning, the fastest I ever got was 14.5 @98. I could feel the power drop off in 1st gear. I tore up the motor and am in the process of building it bigger and badder and this time I think I will go with a hooker max flow. I have headman longtubes and am getting a custom 3.5" y pipe and going to put a cut out on it at the rear of the I pipe and then have a 3" go over the rear into the hooker and then a single exit out the back. Sure the flowmaster sounded okay but it didn't flow worth crap. I'm sure the little 2.5" pipe didn't help much either and that's why I'm upgrading this time around.
How do people think the 80 series is loud? My friend has a 2.5" 80 series catback with hooker 2055's on his L03 firebird and we're baffled at how stock sounding his car is, yet my car was louder than his when I only had some off-brand catback. I can't even hear his exhaust when I'm cruising behind him with my windows down.

Its because of the low compression and peanut cam.
I have a SLP 2 on the left on my LT1 and its VERY quiet. As in, with music and a moderate volume someone can do a full throttle fly in my car, and the other car wouldn't even HEAR the LT1.
Low compression = less noise.
Small duration cam = even less noise.
For info, the cam in my B-body LT1 is about 179/194 duration @ .05" lift. A stock L98 cam is 207/211 @ .050" lift. My compression is about 9.5 or 9.3:1 not sure.
I have hooker 2055 headers, no cats, and a full 3" exhaust.
my flowmaster american thunder series cat back which costed the same as you 80 series (junk) sounds amazing and even my friend who is obsessed with mustangs likes the sound flowmaster is a good company just dont buy their pepboys crap
How do you guys get pulled over for noise so much? I have a 77 K5 4x4 that I drive around everywhere (more than my Camaro lately) it has a 400 small block with an RV cam (stock exhaust manifolds) and TWO Flowmaster 40 series (true duals front to back).
It's loud, and sounds great, I love it.
But I never get looked at even twice by the cops. Maybe because it's a truck and not a sports car?
But please keep in mind doesnt matter how it sounds what should mattter is the flow of the exhaust and from what I had gathered and obtain flowmaster has a poor flow compared to magnaflow and others...
The 43083 is the 80 Series that sounds the best. It's the 3" inlet, dual 2 1/2" outlet, 2 chamber muffler that is of the same basic size and internal design as an original 40 Series. The all 3" mufflers that come with the full exhaust kits are different, larger, and do not sound as good. You also need a high-flow converter to really make Flowmasters (or any exhaust really) shine and some time to "break in" also. Having more ci and power also helps alot too. It is loud, deep, and aggressive on my car.
As for Flowmasters being restrictive and absolutely destroying power to the point where it can be obviously felt.....nonsense. Especially if the rest of your exhaust is set up correctly. I know of more 9-10 second cars running Flowmaster than I can count and some people act like that's impossible because they are just so terrible. Exhaust switches gained some of them nothing and were pointless. Also, if anyone actually read the charts on the first page, it shows you that although Flowmaster was at the bottom in flow, the question is, how much is really necessary? On the power comparison test, compared to the best flowing muffler, Flowmaster made only 4.8 less HP and 1.3 less TQ on a 375 HP engine. Compared to the rest of the mufflers, (which didn't have *open* next to them) you're talking a maybe 1-3 HP/TQ difference at the most. That is gonna be a way lower percentage on a stock or even decently modded L98. It also made more power than no muffler at all and more TQ than some of the higher HP mufflers. Blasphemy! Lies! The moral of the story is pick which sound you like the best and go with it, because it's not gonna make a difference.
I have been told that a single exit is the most efficient, especially with headers (of course). I'm just going to delete the cat and run 3 inch pipe from the y pipe through a chambered tube and then keep it single out the back (tucked under, since there won't be dual tailpipes). I like how these chambered tubes sound http://www.classicchambered.com/index.html
. It smoothed out the raspy sound a bit at high rpms, and really deepen the sound at idle and low rpms. The crackle/popping after WOT decreased to almost no pops/gurgling. It sounds great. I have no complaints.
. Its not breaking in, its rotting out...
I don't get how that is illegal, when you have eardrum tearing harleys putting around with exhausts that are just as loud!
