ok i am looking to get an exhaust system put on my 4.0 and i was wondering what kind of set up would sound the best and give me more power?

 

Sound the best = Duals, with 3" tips.

Perform the best = 2.75" single exit exhaust with a 2.75" or 3" tip.

Backpressure is your friend on a N/A motor. Duals will give you more top-end than a single, but your bottom-end will suffer quite a bit.

Ask me how I know...I've had six exhaust setups on my truck.

 

use flowmasters 40 series, they sound good, and from what i hear, gives good performance

 

i have magnaflow duals on my truck. sound great, good overall performance.

 

Flowmaster 40 super flow

 

I have a Gibson performance exhaust and it sounds great and performes great all the way through the RPM Range.

 

I'm going with 2.5" single from right behind the last cat, out...and stock location with a 3.5"x18" 45degree tip. I'm going with either Flowmster Super 40 (have GREAT experience with those in my Chevy) or DynaMax ultra flow oval....only $20 after $50 rebate with Summit, to see how i like. it might be too loud b/c it IS a rave muffler, but who really cares, louder IS better. weekafter next will be the install date.

 

what about on a 2.3l 4 cyclinder what would be a good exhaust for it

 

Magnaflow allllll the way!

 

holy old post batman!

 

It's funny how people look at different things.
