i think flowmaster 80 series sounds good on my car, but i think that the flowmaster is designed for a more or less stock motor.
if you start making real power, you need a better muffler

 

If the damn things didn't drone so bad, they wouldn't be nearly as annoying.

 

i have a super 44 and it sounds nice. im changing my exhaust again due to a different setup im doing.

 

Hello All!!

I had a Flowmaster 80 series installed on my car about two years ago, and I thought that it was going to give it a throaty rumble sound, ha-ha-ha!!! Fat chance with that, 10 mins after installing the muffler, I left the shop for a test ride, and it sounded quieter than stock, and then the SES light lit up like a Christmas tree, and I got the deaded code 32!!! I believe that the installer broke up the catalyitic converter strata beating on the system, cause my car don't sound like it should, nor does it go like it should, plus the SES light is now on!!! I parked (stored) it shortly after, and haven't got it on the road again, but I am going to remove the system one of these days to check my cat, and see what's up!!!

I read on the internet that sometimes you have to reset your timing, due to the freer flowing exhaust, never heard of that before, but the theory sounds kind of right, can anyone shed some light on that???

Anyone else experience the same problems that I have???

 

I cant wait to take the flowjunker series 80 off my car! It was a free setup and has the huge ***** 4 inch tips.....ewww


my 327ci sounds like poo with long tubes and flowy.......im going single dynomax bullet

 

Anybody able to shed some light on my problem???

 

You shouldn't have to re-set your timing. I had not worries when I have the flowmaster.

Here is what I have for code 32....might be an egr issues.


32

Short between sensor terminals B and C or faulty wiring therein.
Faulty or loose wiring and/or connections at the ECM (Terminals 1, 21 and 22).
Faulty Baro sensor
Faulty EGR valve.
Faulty or loose wiring and/or connections at the EGR solenoid.
Faulty, loose and/or leaking vacuum hoses to EGR valve.

 

Hello slow305rs!!

Yeah, I've checked out the code 32, I just really haven't put much effort into actually getting into fixing it!!! I was hoping that it would actually fix it's self!!

This weekend seems like as good as a time as any, to check it out, and find what's causing it!!

Wish me luck!!

 

After i heard the borla xr-1 on a borlamouth setup I said thats it im gonna make that ... so I been on the search and looking for all the parts I need ... Im gonna use the flowmaster 3" catback pipes and branch it off into dual exits behind the rear end.. in the end it will be basically a borlamouth and everything I have heard the xr-1 on sounds great... heres the link's that set me off and yes i know its a havily moded ls1 but my gosh isnt it sexy!!!!!!!!!!

That will sound completely different on a Gen 1 SBC.

 

Detox's car sounds great. I've been meaning to make a Borlamouth myself. I just haven't had time. Here it is on a 383 also: http://www.youtube.com/watch?v=Ze6fVy753mI

 

Cherry Bomb for the win

 

got 3in exhaust with no cat and some sort of 3in in dual 2.25out with 3in tips think it a flowmaster and i dont like the way it sounds at all for one its to quite wish the was a way to fit true dual 2.5in with two 40series on it had a k-5 with that set up and it sounded amazing

 

Its personnal preference. I love my American thunder cat back. I bought a 3" high flow cat, 3" y-pipe, and shorty headers too. Ive never liked any of the other muffler sounds Ive heard. And I went thru all of the sound bytes on this site before I bought it. I wanted sound first, because its a 305. I dont care what it flows.

Some people like glass packs, and cut outs. I think they sound retarded. And I hate the popping or gargling sound of some of the non-catalytic cars. Ugh.

 

 

of course it will be diff then that ls1 but its still gonna be beefy!

 

I actually love my Flowmaster. To me and my wife it sounds "deeper" than the others we've heard, including other flowmasters we've heard. The guy I bought it from told me that this car had a distinct sound.

 

I have flowmaster's and they're kinda loud but deep. I have no problems with them besides the tips being ugly

 

Buy new tips...summit has some nice Magnaflow ones

 

I just about wore my computer out listening to all the muffler sounds but I bought the Flowmaster Delta force II without hearing it and in my opinion It's the best sounding exhaust out there by far. It's not loud, has no drone or popping at all. Of course my engine is not stock and the Flowmaster might not be the best sounding exhaust for stock engines. To each his own but Flowmaster is one of the biggest names in exhaust for a reason.

THERE is better. (a bank might be Big) but it dont make dont make them last forever..

 

Ok lets see..
Flowmaster.. I have ran flowmasters on 92 RS 305, and 97 Trans Am Lt1.
They sound good. But not going to do flowmaster again. I have been doing a lot of listening to sound bytes on youtube with different setups.
My 85 Z with 305 is ready for a new muffler. I am going to try Magnaflow
with some tips this time around. Once I get it done Ill try to post a link to a soundbyte or video to see how it sounds.

 

Here are some videos with the sound of my Texas Speed & Performance LS1 cat-back Rumbler on my L98, built with a Magnaflow cat, Magnaflow bullet muffler mandrel bent 3" & Magnaflow tips.
Photobucket of videos

 

What?????

I have the 80 series Flowmaster dual pipes & my car sounds awesome at idles & getting up to speeds of around 40 to 55mph.

 

I like that.. Thanks for sharing..

 

Overpriced. and sound horrible.

 

I had the 80-series on my 89 Formula. Sounded like crap and rusted out quickly, especially at the seams. I'm currently running a Hooker Aerochamber on my 91 Formula and like it much better.

 

Here's mine. It's a Flowmaster Force II. http://s188.photobucket.com/albums/z...g3-4-10001.flv

I have the 80 series on my IROC & I love it. It sounds great. But it's rusted & so is the long pipe too. I have a brand new set up sitting in my apt. though and I'm buying a brand new pipe soon to replace the old one.

 

What's wrong with the flowmaster sound? I used thrush welded 2 chamber flowmaster 40 series copies: http://www.youtube.com/watch?v=hyRWfFqCQaE

 

all depends on what you have for engine/cam etc... here is mine with the 3" single "american thunder" flowmaster system (iirc its an 80 series muffler)

I have a pretty stout 383 that has only 17 miles on it. May mellow out a bit more once it breaks in and such:

My IROC is pretty much stock right now. I've listened to Borla, Magnaflow, and Flowmasters on youtube. I prefer the Flowmaster 80 series sound. Magnaflow sounds like a motorcycle exhaust. Flowmaster sounds like a true dual set up. Just purchased the muffler from Pep Boys, can't wait to get it installed with new tips.

I guess it comes down to personal taste.

 

I have a 91 TPI 5.0 5 speed with JetHot Hooker 2055's and 3" Magnaflow Cat..
I got the 3" Flowmaster system, the one what is 1 in 1 out... and it was one of the last ones that came with the Race 30 Muffler... I prefer the 1 in / 1 out, cuz it flows better than the 1 in 2 out and I personally don't care to see the tail pipe on my car, I actually used heat primer / paint and made it black... I like the sound... not too loud, not much drone unless high in RPM and gettin on it... I'm sure they're are nicer / stainless steel systems, but it ws only $236 delivered...

 

My Force II also has the race 30 series and I got it about 3 months ago.

They guy @ Flowmaster told me they stopped making those and was surprised to find out I had one... "old stock" or BS story... anyway, one of the pipes in the kit hadn't been stretched at one end, they promptly sent one to me... Again, for the price, I'm good...

Rafael

 

They still have them on the web site. They are under race mufflers. Who knows, we have them anyway.

Mark.

 

Well I hate Flowmasters. I've tried them on many cars of mine and customers cars. Then sound like crap to me, too loud all the time, too much drone, the rust real fast and too much cabin vibration. Also look up the flow ability, when they advertise they only talk about the sound but never the flow increase. That's because most of their mufflers don't flow that well at all, look it up. They barely flow more than stock high performance mufflers and the real hp gain is when they upsize the pipe diameter from stock with their systems. I've changed all of my mufflers to either Magnaflows or Pypes cause they are high flowing, stainless steel and the sound is just right when they set. IMO

 

I have edelbrock exhaust on my 84 camaro, I dont realy like it, honestly it sounds like a really loud washing machine. it only sounds good when you floor it, maybe I dislike the edelbrocks because on my 86 camaro ( the one i had right before this 84) I had flowmaster cat backs and they sounded bad ***

 

I noticed a lot of people that hate Flowmaster only have experience with the 40 series and all the "data" that has been posted is either from 40 series or unmentioned.

The 40 series in my (and many others) opinion is the worst muffler offered by Flowmaster. It is their budget muffler mostly offered in shops like AutoZone or whatever your pick is. Try getting one of their better quality mufflers instead of comparing their cheap stuff

I have a Flowmaster catback on mine, best sounding exhaust I've ever had.

 

I hear you on that but I've had their 40, 50 and import series mufflers and their catback systems on a camaro, Tahoe, S10 blazer, mustang gt and a bmw 525. All of them sounded like crap and all of them rusted out fast. In my dealings with the mufflers I found out that if you have a stock exhaust system or low hp car and just change the muffler the sound is not too bad but if you up size the pipes, remove the cat or have some hp with their mufflers it sounds like crap to me. Why would you want to pay $70-$120 bucks for a muffler thats going to rust out and sound like crap when you can get a free flowing stainless steel one for $60-$70 bucks that sounds better to me. It was a thread on LS1tech were a guy with a modded WS6 was running two flowmasters 40s with dumps and changed them out to Dynomax ultra flows and picked up 24whp. Pypes and Magnaflow for me. JMO

 

Thanks for proving my point. He was running 40s, Flowmaster's worst flowing muffler. It's his fault for being cheap.

My FM isn't rusting at all. You do know they sell stainless steel as well, right?

 

I ran the 40s, 50s, import and their cat backs on different cars of mine. I think the F-body had the 80 series and the Tahoe had the 50 with dual in single out. I know they sell the stainless versions but think about it, the stainless 40 series goes for $80 bucks and the Stainless pypes goes for $60 and the magnaflow will set you back $70. Then have the mufflers flowed. Some like the crackle and drone some don't. To me they just are too loud and don't give me the performance that I'm looking for and my customers feel the same way. imo

 

For the price of a new SS 3" system from Magnaflow I would never buy anything else. Although that's not to say if Borla ever made a cheap system that was also SS (Yeah right) I wouldn't buy it, since Borla is my favorite amongst them all. But Magnaflow for the win in price, size, flow, quality.

P.S. I am not posting that I hate flowmasters either, I just prefer other systems for my car. Plus given the right motor and length piping, cherry bombs, flowmasters and cutouts can sound very clean AND mean.

 

That's your preference. But don't give us examples that prove my point :P

 

What point did I prove Tekkitan. You said in your opinion the 40 series was the worst muffler flowmaster offered and try using one of their better mufflers. What I was saying was I have tried some of their better mufflers and catback systems and I still didn't like them for various reasons ( cost, sound, performance and so on). Unless they have a secrete muffler that they don't sell to the general public I've tried or heard what they have and for me I will never buy a flowmaster muffler again. It's better sounding longer lasting higher flowing and cheaper mufflers on the market now. But other people may like them and that's ok

 

i had a iroc with a 305 5 speed g92 that had flowmasters minus cats. it was the meanest sounding car ever! my current iroc has a ls-6 with flowmasters that sounds like crap. i just put on magnaflow's that sound great with the lt's and ls-6. i think it depends on your setup.

 

As some have mentioned, your setup can make alot of difference.

Obviously headers, pipes, muffler, tips will change.

But this last fall I changed my heads alone(steel to alumn), and it changed the tone of my exhaust.

While adjusting my tune, I noticed my "pop" and "gargle" have changed. You can also adjust your idle sound by changing your timing and fueling. (lean and rich make 2 different sounds).

That being said, my car currently has cheap shorties and an 80series on it and sounds decent. I plan to change my whole setup over the course of the year. Ceramic headers, borla single in, single out, no visible tip(s). I expect it to sound like a complete different car this winter.

 

Well, Big Dog Chevy, let me quote you on what you said since you can't remember what you said:

That is proving MY point. Also, I don't see any flow numbers from you. All you have complained about is price, sound and the mufflers "rusting out". I see nothing from you to prove that performance is less with their higher quality mufflers.

 

I have always preferred the sound of flowmasters over borla. I hate the sound of any crossflow however. I have the singe in single out 3" on my GTA. It sounded ok with stock manifolds and gutted cat. but when I put on my longtube supercomp hookers and offroad y-pipe, it sounded awesome. It had a high pitched raspy banshee shreak sound, which I like over the bassy sounding borla stuff. I have heard some bassani exhausts that sound pretty good. I am probably going to run dual spintechs oval 3 1/2" pipe with my new engine, not set on it.
