i have a 92 Z28 with a 305 i was looking into replacing the muffler so it sounds better but i would like to get some opinions before i buy a muffler i would like to get a muffler that has a nice deep rumble but doesnt have the wierd noise that most 3rd gen makes when the idle is coming down after a rev. i heard the 40 series by flowmaster is pretty good but i would appreciate it if anyone had any comments thanks!!!!

Flowmaster and Magnaflow both make a crossflow muffler for f-bodies. If you want aggressive, the Flowmaster 80 series is a direct replacement for your stock muffler. Magnaflow mufflers tend to have a smoother, more mellow tone.

Go with the flowmaster! you will love it and never look back on your descion over the magnaflow

thanks guys
but which series of flowmasters would you recommend???

I enjoy hearing a 40 series go by, but wouldn't want it in my car... too loud... I got a Flowmaster 1 in 1 out that actually came with a 30 series (no longer made) I think that 1 in 1 out now comes with Super 40 (less drone and deeper tone than regular 40 series)....

There are so many factors that 'make' the sound, but Flowmaster does have samples on thier site...

As for flow, I can't say which one flows better... ???

Raf

if your looking for which has the best flow, id say go hooker aerochamber, its the only muffler that has the numbers to back it up that say it outflows the competition, and the sound you get from it is really nice. you get a nice growl when you hit the throttle but it isnt so loud that you cant have a conversation in the car.

flowmaster is nice, but in my opinion it doesnt stand out in terms of sound, everyone around here has "flows" or so they call it, and its nice and all but when you see a 92 vw golf pull up next to you with a flowmaster it just kinda feels like its another mickey mouse muffler that ricers get their hands on. but if you like the sound i say go for it, and i hear the 40 series sounds awesome but gets boring quick.

my buddy has a borla, and it sounds great. even though he only has a muffler while i got the whole exhaust done on mine with the hooker, his seems to have a deeper more growl like sound at idle, while mine has more of a light growl and snarl.

The Magnaflow probably flows better, it's actually a straight through muffler. Flowmasters have a series of baffles that deflect the flow of the exhaust gases. If you want to stick with a factory appearance (dual outlets) you'll probably want to go with the 80 series crossflow muffler or Magnaflow's equivalent. Either one will sound fine. The Flowmaster will probably be louder and have more interior resonance. I also agree with the guy above me: Borla exhaust sounds pretty good.

i really appreciate everyones input
but what would you guys say would be the best at a decently low price cause i am on a tight budget

I think you can get a Flow 80 series crossflow for around $80 bucks. Look on Flowmaster or JEG'S website for accurate pricing. You'll save money on installation because it's a direct replacement on f-bodies. Here are some links for both Flowmaster and Magnaflow. Both websites also include sound clips. http://www.flowmastermufflers.com/80_series.html , http://www.magnaflow.com/02product/u...asp?shape=oval

the magnaflows actually down flow as good as a chamber muffler. the problem with it being straight though is that the internal diameter gets smaller inside the muffler and has all those small perforations in it which doesnt promote flow, the chamber mufflers dont get small once inside the muffler and instead just have a series of little chambers or walls inside that tell the exhaust to go a certain way.

if you want the best bang for your buck, get a summit muffler, those are very good too, but i forgot who makes them

Summit Racing perhaps?

I've heard that it was the max flow muffler, not the aerochamber.

perhaps, how long ago did the max flow come out? i bought my aerochamber around a year ago so it might have changed

i would get flowmaster if you are in a tight budget because magnaflow is more expensive

i jsut bought a brand new magnaflow kit on ebay for 340 shipped. you cant beat that

if you only replaceing the muffler go hooker or flowmaster if replaceing the full cat-back then there are a lot of options dynomax being the cheapest jegs also has cheap direct fit catbacks for our cars where as summit dosnt carry a summit branded catback for us the jegs kits sound alot like flowmasters id recomment the jegs kit honestly if price is of concern

but i have a 2 differant flowmaster mufflers for my car i swap them out depending i feel like hearing i have an 80 series when im going out on the town and i have the 30 series from the cat back i have it has a nice sound outside the car but inside sometimes it sounds like im driving an astro van great for road trips but when i installed the headers the 80 series got really loud and drones but now the single out 30 has the tone the 80 had but without the drone

im not sure what you can do about the poping sound these cars make when letting off the gas

As others have said...everyone and their mothers put flowmasters on these cars. I have a flowmaster system that was on my car when i bought it. I will probably leave it on until it falls off and then replace it with something better. For the money it sounds ok but its pretty loud and drowns a good amount on the highway. If you do a lot of highway driving take that into consideration. My car is only fair weather though so i dont care.

I have two 91 camaro RSs One has a 305 with magnaflow catback exhaust and sounds mean and loud the other has a 406 with headers and flowmaster and doesnt sound mean or loud.

Exhaust/Mufflers are really a personal "taste" with regards to sound. What sounds good to me may not sound good to you. I have had both Flowmaster and Magnaflow on my car. Currently, I am running the 3" stainless Magnaflow cat-back with a 3" high flow Magnaflow cat. I absolutely love the sound. Deep, mellow and a nice aggressive sound at WOT. I found the Flowmaster to be a bit more of an aggressive sound (A BIT MORE,lol) and it didn't have the deep sound that i wanted.

Again, it's personal preference. As with performance no matter what you put after your cat will be far better than factory and we're all limited to the type of y-pipe even with headers and a decent y-pipe. My y-pipe used to be the headman, but then I had a nice 3" mandrel bent y-pipe made and WOW, it made a huge difference.

Good luck!

I love the fact that Magnaflow is stainless and a lifetime warranty when installed by a Magnaflow dealer. Can't beat that. Mine has been on for a year now and she cleans up beautifully!!!

It's a little more than Flowmaster, but when you never have to worry about replacing it then it's worth it. I have had two friends have issues with their Magnaflow setup (nothing major) and Magnaflow sent them a complete replacement no questions asked. Great company.

i wanted to add hooker makes a great sounding catback
i have a hooker setup on my 94 roadmaster wagon sound great the tone is very nice its tone in the car is far better then the flowmasters i have on the camaro and the hookers sound outside i never got tired of it

ive also noticed catback kits always sound better then just buying the muffler maybe they use a thinner pipes with catbacks or something but they always have better acoustics then buying just a muffler

Its the better flow. Stock exhaust are crimp bent (forget the correct term) where as aftermarket exhausts are mandrel bent so that the exhaust gasses do not get slowed down by crimps in the pipe. Also most aftermarket exhaust is a much bigger diameter than stock. I have a 3 inch system on my camaro from the headers back.

I got my Magnaflow exhaust to be quiet at idle (like a corsa on a vette) and loud as hell at WOT which it is. Kit Part # 16829

Flowmaster to me is very droney (is that a word), and very raspy, and even more raspy as they break in (that noise you hear after revving, so you may not want flowmaster).

I think going with a Hooker aero or max flow is your best choice. Kind of like best of both worlds going with Hooker I feel.

Let us know what you choose, and please provide a sound clip. A lot of people get new exhausts on here or mufflers but never get a sound clip.

Take care

well i really appreciate all the input that everyone has been giving me and i guess i just have to shop around and see what i like. i am just gonna get a muffler for now because i will most likely take the cat out and just get custom tubing done at my cousins shop down the road. i also have not decided if i am gonna keep the stock 305 or put something else in it so im not sure what i wanna do with the exhaust yet. will an exhaust for a 305 fit a 350? or sound the same? well once i decide what i wanna put on ill figure out how to put a sound clip or video on. again thanks for everyones input!!

The exhaust should interchange between a 305 and a 350. As for a sound difference between the two engines, there probably won't be any. They are similar engines with the same firing order.

If you can go around your town/city and check out some peoples exhaust, even if its a different car the sound will be relatively the same, not completely, but close to.

You will definitely tell a difference between a 350 motor exhaust and a 305. The 350 will sound so much meaner.

Magnaflow has a video clip with a 305 camaro and one with a 350 TA (Both 3rd gens). The TA has so much more sound than the 305. Actually the guy with the 350 TA is a member here.
