I have a friend that has an 02 Chevy 4x4 with a 4.3 and the muffler is getting bad and he wants to replace it. Anybody have any recommendations as to who offers a good cat-back that will sound decent and not lose any power, possibly gain a little maybe?

 

I will ask my brother in law what he has on his truck. It actually makes the 4.3L sound like a V8 at idle.

I'm going to move this to the compact section as you might get a better answer in there.

 

Not sure of the brand, but I have heard a few 4.3's that sounded okay. I almost thought it was a 4.8 or a 5.3. That is, until the green light popped

 

Cool, thanks, Yeah, he just wants something relatively inexpensive without sacrificing quality, hp, and especially TQ.

 

I just had some 3" tubing a 3" bullet & a turndown welded on after the cat with the turndown before the rear axle, sounded like **** but in combination with shorty headers allowed me to gain 2 tenths & 2mph...that was with a powerdyne blower though.

 

Yeah, 3" is going to be way to big on his, he'll lose TQ down low. Its just a DD but he'd like a little sound to it.

 

i will say before the 3" i had a dynomax catback system...very quiet, rusted through within a year...not really impressed with that fwiw.

 

I have a dynomax catback and like it a lot. It is very quiet which is what I wanted for hunting and off-roading. It does the job very well and has no rust issues at all, but I live in california so I dont get as much rust as others in the country.

 

mine rusted from the inside out(condensation) if i wanted quiet I wouldve kept the stocker

 

LOL, good point.
