Hey guys. I found out about a week ago that Flowmaster now makes a dual outlet 40 series muffler, which kicks *** because its two chamber and has that original Flowmaster sound. But, i've heard alot of good things about the Hooker Aerochamber mufflers. I will probably just buy a muffler and get the muffler shop to run the pipes, saving me alot of extra money from just buying a cat-back. I plan on getting a Catco high flow cat also.

What would be the best muffler for a good, low rumble at idle, but sounds awesome when you feed the speed to your ride? My dad runs Flowmaster 40 series on both of his cars, but they have a 350 and a 403, so i really can't compare.

I like the Hooker Aero-Chamber a lot more because it sounds great and unlike any other car around here. Its not real loud at idle but noticeable and when you step on it the thing gives out a nice loud "growl" Thats the only word I can use to describe it. I hear Flowmasters every single day on cars. Why sound like everyone else? If thats the sound you like though then get the Flowmasters, I'm personally tired of hearing them

 

I just got the Hooker Cat-back and love it. I believe there was a post not too long ago with a soundclip of the Hooker cat-back w/the aero chamber muffler, probably about a week or 2 ago.

I think im going with the Hooker Aerochamber muffler.

Im gonna get the muffler that way the muffler shop can run their own mandrel-bent pipes to adapt the the different parts im getting, and not having to deal with other situations. How do you think this muffler will sound with a Catco high flow converter? I will probably get 2.5 inch pipes or smaller because of clearance issues. What are some good looking tips for 3rd gens? Look in my sig. for car info.

Flowmasters dont sound the same all the time. There was a post about someone who had a 80 series that was quiet. Where mine is hella loud.

Definately flowmaster 40 series,but what you really want to do is cut out the cat and run 3" or 4" piping from the y pipe to the muffler,I have 3" on mine and my friends say you can hear me enter their neighborhood,its loud as **** and sounds really bas ***

You wouldn't want to go with anything above 3" if you don't have the HP to back it because you will actually hinder the performance of your car. I believe if you have between 250-300hp you should go with 3". There was a post a while back, like a month or so, about what size you should go with according to your HP.

See, right now my car is around 170 HP, because its bone stock. But i figure after adding the muffler, high flow cat, K&N filter, and eventually headers i will be around 210. Then I will probably get a CompCam which then i should be around 230. So should i get 2.5 piping?

Another thing is I HAVE EMISSIONS, so i don't believe i will be using a straight pipe in place of the cat.

MetKiss316:

Don't expect to get a 40hp increase just from doing your all of your exhaust: headers to tailpipe. Your going to need to do some intake work as well.

what am i doing?

hee hee where have you been thats been around for a little while . yes it does kick a$$ (I have one on my truck) but its not a crossflow so it really wont work on your car unless they can custom make pipes for you. Good luck

What about the American Thunder cat-backs. They seem pretty cool, but they dont have dual outlets for ThirdGens. Any way you can get it with dual outlets?

How much would it be to get custom pipes for the 40 series?

How does the Hooker compare to the Flowmaster is terms of tone and sound, and performance?

doesnt it seem alittle beligerant to buy small pipes because your cars low hp? because then when you go to put more hp adders on there, then wouldnt you lose, or atleast not gain as much performance? yknow what im sayin, put a big exhaust on now so when you do put nice shxt in there, itll handle better. eh?

 

I've got a Hooker Aerochamber setup on my 87Z with TES headers and a Catco 3" cat. My old 86 IROC (now my brother's) has a flowmaster dual out cat-back (don't know series) with TES headers and a catco cat as well.

Both sound pretty mean, but I prefer the Hooker setup. It's louder at both idle and cruising, as well as having more of a growl to it (some of that is motor I'm sure). I also like the Hooker cat-backs quad tips over the turn downs on the flowmaster setup.

Oh, and go for 3". Makes no sense to go to the trouble to change everything and not do it right...

And you probably will get close to your power goals. CHP got 199 hp out of a stock LG4 with only headers and exhaust work. They also gained a good bit from the intake and cam work before addressing the heads. You can view the article here: www.inter-scape.com/ray/305buildup.htm

dude, i have the 40 series on my car. just go to an exhaust shop and have them bend pipes for u. i have dual exit too. i know the american thunder exhaust can be had with two exits in the back too. i also had the dynomax high flow cat too. and 3" pipes. it is really low at idle and screams at WOT. and i dont have headers yet either. i would go with the hooker if u are only getting a muffler and the 40 series if u are getting headers too. 40 series and headers sound AWESOME!!!! i have heard it before. i have never heard the aerochamber though. either will be awesome but i can only vouch for the 40 series. very awesome!

Uhhh, I just bought the 3" American Thunder with dual 3" stainless steel exits. Look in your jegs catalog. It sounds hella nice and loud! At first you get quite a bit of snap, crackle, pop but it quickly goes away and becomes deeper and deeper. I've been getting hella compliments with it. It's really loud!

Jono: Those clips sound exactly like what I want. What other modsa do you have and what kind of engine? Thanks.

PS: Anyone got clips of Borla exhaust on a thirdgen?

The dual outlet 40 series Flowmaster is made fora pickup truck. It has one inlet and two outlets on the same side of the muffler. Hence, it will not fit on your thirdgen F-Body if you have the stock exhaust setup.

Therefore, a comparison between a Hooker Areochamber (crossflow muffler) and a Flowmaster 40 series (straight through muffler) is not revlevant.

The only Flowmaster that will fit a thirdgen f-body with the stock exhaust routing is a 80 series (Crossflow = 1 inlet, 2 outlets on opposite sides). This is the muffler included with the Flowmaster American Thunder Catback.

Anyhow, I personally like the Hooker Aerochamber a lot!

Don't really know, I had it all put on at once, I'm sure the headers added some volume but I couldn't tell you how much. Needless to say I am extremely pleased with the sound, and those mp3's don't do it justice.
