looking to get something for mine and want some opinions before purchasing...

what does everyone have, and how do you like it?

i've been lookin at the dyno max super turbo, i heard the are pretty good.

 

Ive got cat-back duals with a Flowmaster 50 Series mufflers. Its pretty loud when acclerating but its not very loud when cruising at a steady speed.
All I can say is that when I pulled up to the gas pump today there was a guy gassing up his brand-new GTO next to me and the whole time he was staring at my truck.
Octane

 

I have a 40 series Flowmaster with dual pipes out the rear. I've been very happy with it. Just use stainless tips like I did, the chrome ones will rust after a while.

 

I have true duals & flowmaster 40 series. Its loud if you get on it but its not bad at highway speeds. I ran mine out the side before the rear wheels.

 

Lovin my 3" in, 2.5" dual out magnaflow... Nothing but compliments, and it's not too loud... nice and mellow

 

I had the muffler shop build me duals after the cat, it's a Flowmaster 40 with 2 1/4", I have 24" x 3" tips behind the wheels 45 degrees out the sides, the 5.4 in my van sounds different than the trucks done with Flowmaster cat backs, mine seems louder.

 

I got pacesetter full tube headers and a pair of flowmaster big block mufflers...a true dual exhaust...a full 3" from header to tip, no cat...nice and mellow sound...and cant get a more free flowing exhaust

 

I went with Gibson stainless headers and a single exit cat back system. Sounds deeper than stock at idle and nasty when you hammer on it. Makes people take notice.

 

Supertightexpo,
I was thinking of doing the same type of setup for mine. What kind of performance increase did you see?
