Exhaust system for v6

[TruThug]

I have been looking on the Internet for awhile and can't seem to find any exhaust systems in my price range. I have a v6 and I know it won't sound like a v8 but I just want a little sound when I give it gas, the factory exhaust just isn't cutting it. If anybody has a exhaust system for a v6 that is just sitting around please let me know. Thanks

If your 3800 has the factory tubular manifolds on it now, you basicly already have shorty headers on it.

I ran with a cat delete and a late model z28 single inlet dual outlet muffler on my 01 Camaro.

Sounded pretty good without the heavy 3800 drone.

Don't all the exhausts mount to the stock y pipe location which is the same on the 6 & 8 cylinder cars?

[Smittro]

No they are not the same..

3800 cars don't have a "y" pipe.

The 3800 factory exhaust has a 3" collector. (there's a difference).

The collector pipe is ~14 inches long prior to the cat.

On the 3800 cars the intermediate pipe mounts after the cat.

Ls1 cars have 2 cats 3800's have one.

In other words both the left and right bank exhausts dump into a single collector pipe for the 3800 pre-cat.

Explaination:

A "Y" pipe generaly has a single exit that is roughly the same diameter as the pipes coming into it.

A collector usually has an exit much larger than the diameter of the entry pipes.

So with me not knowing anything you just said cuz im not much of a car guy would can i do to make it sound good? I was told just take the headers off but i have to pass emissions this month hah

[goof4080]

Ok. I don't care about the terminology... but thanks for that.. what I was trying to say is can't he buy any fbody catback and it will match up or no?

nope..

As is said they are NOT the same.

A 3800 cat back is different than an ls1 cat back.

As stated in the part you don't care about.

[goof4080]

Show me where you stated the cat back was different? You only stated the 8 does two cats to a y and the 6 merges before a single cat...

[goof4080]

I was jist asking...and yes I'm grumpy today. Sorry!

If you just want a more loud or throaty sound change the muffler out.

There are plenty of single mufflers you can use in place of the overly quiet stock single inlet single outlet muffler.

post 4.. The v6 uses a goofy setup. the cat inlet is 3" but the out is ~2-1/4 "ish".

It's kind of an odd ball size. But yes the LS1 cars have their cats mounted right @ the manifolds.

The 3800 has a single cat mounted much further down stream, and it's set up more like a collector with the 2 inlet pipes side by side rather than coming together like the LS "y" pipe.

I was jist asking...and yes I'm grumpy today. Sorry!

It's all good..

[goof4080]

Cool. OP. I just remembered I used to have a buddy with a 3800 camaro. He ended up having them replace the muff with a flomaster maybe and some good looking dual 3" tips

Funny you mention that ..My moms (old lady car-as she calls it) 01 Buick LeSabre has a 3800 recently while at the shop i got to see underneath it for the first time ,LOL i was suprised to see this big-ass 3'' pipe (collector) under their! Wow suprised me. I was like ..go mom! and if you step on it ,it does go.....

Word of advice.....DONT do anything that will F-up your passing emissions...I DID and though i love the power.sound etc...of my mods its a BIG BITCH to pass every other year.alot of members dont have to worry about that so.....( yeah i know ha ha on me....) so stick to the mods that WILL pass, theres plenty of options other then messin with emissions.

What about him using a cut-out?

It will sound crapy.. The l36 has a drone that is just horrible without a cam with a little lump to it.

They sound like a dump truck open exhaust on a stock cam.
