I have decided to go with a Flowmaster series 80 muffler and 2.5 inch pipes. I would like to hear what you have to say about it. Sound quality idle, open throttle, and normal driving. How will it sound compared to stock 87' exhaust. I'm not looking for insanely loud tones but muscular sound. (Like the car has some nuts) If any one has a sound clip please post it cause i'd like to hear it. Any one with any experience with these mufflers please respond. Thanks ahead of time.

BTW i only have a 305tpi and don't plan on headers.

Just installed this on my carbed 305 and it sounds great. The idle is a lot deeper and at driving speeds and WOT its pretty loud too. If you're looking for something that sounds like a drag car, this isn't it, but its great for a daily driver.

Hey stupid Did you do the install yourself? If you did how was it? Pretty easy or what?

I love the sound of the 80s Flowmaster. It was deeper and definently louder than my stock exhaust. Never really had the time to break it in either before I got the cut-out. Now the cut-outs sound is a whole other story

chio987

i have a sound clip i'll have to get on the PC but i really can't say i liked it. i mean it was an easy install same size everything but i can't say is was muscle car sound. i would recomend getting 3 in tail pipes for it, they should slide OVER the outlets for the muffler and give u a little better tone and a better look. hope this helps and i'll try to get a clip of it to u, the only thing that might make a difference is i have a 305 4brl HO and i bet u have a TPI so the idle might sound different

I actually like the sound of the Flowmaster on my IROC. I don't like the way it sounds on my ls1.

My IROC is the 5.7l and I have headers. It sounds very deep and badass. There is only one downside to it...between 1600-2000 rpms it sounds like a baffle is broken and rattling around inside. Very loud and very annoying.

Alright...Thanks so far for the replies. One other question, if I don't plan on doing any major engine mods will a 2.5 inch pipe be sufficient? Any other comments are welcomed. Thanks again.

I have the Flowmaster 80 series crossflow muffler installed on my LO3 using the Stock exhaust manifolds and an SLP Y-Pipe and it sounds awesome. After I installed the Cowl Induction hood, my RS Camaro looks and sounds mean. Mustangs, Supras and hondas always pull along side and try to intimidate me but, after I Rev the engine a couple of times they go away.

Mine sounds great. No golf ball rattleing as some people describe



And it's not close to being quiet

dual 2.5's are plenty big. Your I pipe more of a restriction. I'm not big into the whole flowmaster sound thing. I have a Ravin sound clip in my sig.

after i realized that my stock exhaust i-pipe was 2.25 it was very easy, all i needed was a reducer and new tailpipes. Total cost was like 90 and about a half hour of work.

i love my 80 series

Jose'sRedTA

So far i like what I hear. I'm going to put the rectangular camaro SS tips on there. Does anybody know what that will do to the sound. Probably lessen it a little but I like the looks of those tips. Thanks...and keep the replies coming.

Jose'sRedTA

Anybody got pics of the tips that might help give me a good idea of what looks good on a Trans Am. Thanks

FastBack

I would go with the flowtech, they have a lot of good products and they are made by Holley just under a different name. So you know the product is going to be good.

heavy_chevy29

i love my tips. they are 3 1/2 inches.

Jose'sRedTA

I like those tips...how does the 3.5 inches effect the sound of your exhuast? Looks great!

89IRO

Ahh, not another flowmaster.

Jose'sRedTA

LOL...I know some of you out there are purists and like Hooker or something like that. But flowmaster is well built and not that expensive.

OBTW...I do agree that there are others that sound better!

91blackz

Nothing wrong with this muffler i just wish i was alittle louder but has a great tone to it!

IROCThe5.7L

Not another useless post

89IRO

Not another useless post

Ahh, what a funny guy. Not another useless muffler, that's what I'm trying to say. And no, I don't think flows are well built at all, I've seen them in person and don't like them. Get yourself something a lot better like a magnaflow or hooker, never heard a hooker, but a lot of people here like them. But hands down, IMO thee best muffler out there is spintech. I've got the 343SC. Costs a little more than a flow, but you also get what you pay for. This muffler is practically bullet-proof. Anyways, if you guys go with flow and are happy with it, then great. I also hate how they sound. Everyone at my school has a flow on their cars and they all sound the exact same, just the boring ol un-clean flowmaster sound. Just thought I would throw another option out there for you guys before you buy one of the most restrictive mufflers out there. Bring it on fellers! Have a nice day! :lala: -89IRO

Whatever floats your boat.

IROCThe5.7L

Can you please show me a dyno sheet of the same car with a spintech exhaust and a flowmaster exhaust, that shows a gain with spintech.

89IRO

No I cannot. I know flows suck, and that's all that matters to me. As long as you guys are happy and I am too, then that's all that matters. I'm just saying what I have heared from reliable sources and personal experience seeing flows up front. I don't care what anybody else thinks, cause I know which company is better so that's that. Later.

Or you guys could quite whining about flow on a muffler and just get a cutout which will give you better performance than anything and you still have that awesome flowmaster sound when closed.

FastBack

heavy_chevy29: where did you get those tips? do they improve your sound or not? those are sweet!

Jose'sRedTA

yeah i'd like to know also...the look great! What about the sound?

IROCThe5.7L

heavy_chevy29

when i got the exhaust welded on, i told the guy what i wanted and he got them. i think they are ravin tips. the exhaust was done at midias. they are 3 1/2 inches and go almost all the way back to the muffler. i don't know if it really affects the sound. all i know is that it sound awsome.

89IRO

A cutout would be nice for performance, but around here, that means a big fat ticket. Maybe if you live in the country or something. Plus, an open y pipe might be cool for a few minutes, but that could just get irritating any longer than that. But then again, you could just put some flows on and get that "awesome" sound. (Relax guys, just my opinion) -89IRO

This whole discussion makes me laugh LOL, Flowmaster guys vs. every1. If your muffler was really a better product don't you think that you would see REALLY fast/built cars running them instead of Flowmaster?? I don't know if you've been able to be around or know people with FAST cars, but guess what?? They almost all use Flowmaster. The only other muffler I've seen used on such applications is Dynomax because they do flow good, if not the best. On a stock or mild engine even if you do get a muffler that flows a few CFM better there is practically no difference or a noticable difference, if it even really requires it. I guess I better go and tell all the people here with 10-12 sec. Camaro's, Chevelle's, Nova's, Firebird's, GTO's, and whatever else that they better take their Flowmasters off because they are keeping them from running fast. But then they wouldn't sound good anymore. The entire "Flowmaster doesn't flow enough" is just ridiculous. I don't know what some of you guys think you are running, BBC's used for high dollar street racing?! The chambers inside a Flowmaster might seem restrictive and not as good as a straight through design, but the fact is that they flow plenty. The exhaust travels all over through and around the chambers making that sound but the exhaust doesn't know the difference, it just goes out like it should. I see people running cut-outs, and with them closed you would think that the exhaust would flow into the closed pipe section causing a restriction and slowing you down, but that is not the case. The exhaust doesn't know the difference and flows right past it to get out. The Flowmaster chambers are not that restrictive, straight through is better, but Flowmaster flows plenty. Get what you like and leave others that like another exhaust (the most popular 1 at that!!) to theirs, there is no reason to comment against them so much everytime it is brought up. Most people like them, thats just the way it is.

Magnaflow is straight through as well is dynomax. Spintech, hooker, and flow are the only ones with just metal stuff inside. Yes, the nice thing about those magnaflows and dynomaxs is that they are straight through, but over time that fiberglass ceramic stuff inside can burn out and lose it's sound. With an all metal muffler, the sound stays consistent throughout it's entire life. I was just letting the guy know who started this thread (assuming he didn't already buy it, but was planning on it) that there were more options out there. And no, on a 250 HP engine, you probably won't FEEL a difference with different mufflers. It all comes down to sound I guess, and if you want to be like everyone else or if you wanna be different. All of you already know I don't like flow and I said why, but if that's what you have and love it, than good for you. And who am I to say flow sucks? Just my opinion. Go to any large racing event (drags or circle) and the spintech name is everywhere, but it isn't really known on street cars yet. Got to go eat my cherios now. Later. -89IRO

I don't think i would consider this bashing: " and if you want to be like everyone else or if you wanna be different." Now I need to go check up on that I pipe.
