do they make a true dual exhaust .everywhere i look i only find cat backs and 1 into 2 i just want true dual even if i have to have cads.any links please .i want to come off my shorties gibson by the way .

 

custom is the only thing i know of

 

Like you said, custom is all there is for true duals.

 

i just got mine done, well worth it in my opinon!

 

lt headers and x pipe true dual system here!! no complaints.

 

so the majority of the people are running cat back systems for their performance trucks.i read a post on her that said single 3inch or 2.5 dual are they talking about tailpipes only. what is suggested for my application ?6.0 with descent cam and gib shorties factory cats 2.5 pipe then what to use after that to get good breathing /flow?i deff. want dual tailpipes if ok for flow .i feel like i need more flow its holding back.my y pipe is off my origanal 4.8 motor if thats any help .flowmasters are too obnoxios .i dont know what gibsons or dynomax sound like .any links or personal info would help .by the way this forum is great .

 

Look here for sound clips:

I'd go with 2.5" true duals and whichever muffler you prefer from the sound clips.

 

try corsa for muff its prob the sound your looking for

 

That means the whole exhaust is that size. (not including tips)
Personally i'm going with LT's ORY 3" pipe 12" Bullet for a resonator and a 16" Borla xr1 for sound. then just dumping it under the truck.

 

I had on my 05 4door 1/2 tonner, true duals and an H pipe that I had a guy fabricate for me. I just cut the pipe where the two banks of cylinders come together, Y, and ran two 2.5 inch pipes to 2 dynomax super turbos, (14 inch X9 inch case), and then two 2.5 inch tailpipes criss-crossed to equal the length of pipe between two banks of cylinders. This gave me a double balanced system. I use the H as a balance tube, and I ran the drivers side bank of cylinders tailpipe out the passenger side, and vice versa. This took care of the drivers side pipe coming across to run down the passenger frame rails. It sounded great and ran good. Never dynoed it or anything. I put the same setup on 4 other trucks and have liked the way they perform. I have a few pics of it from my 8.1 liter.

The H is not in the optimum place, but I put it as far forward as possible. One the 1/2 ton, it was right where we cut out the Y pipe.

For a 6.0, I would not use any bigger than 2.5 inch pipe dualed, with an H or X. X is better, but harder to get in there.
