I need some help deciding which exhaust to get for my NNBS

I want Dual and a nice sound

I am looking at:

14199 2007 5.3L Silverado/ Sierra EC/Std bed & CC/SB- SPORT dual under bumper rear exit w/ single 4" Pro tips

and

Cat back system that GM offers.

Who else makes something good?

Check the engine and performance section and look about about half the threads.:rofl2: It is the biggest struggle: What type of exhaust? Flowmaster vs. Magnaflow. Corsa because it does void GM warranty. spintech, dynamax bullet, etc., etc. Pushing an '07, I don't if anyone can speak for the sound on those trucks, but I do like the setup you plan on going with: Dual rear exit.

so your saying that all cat backs voids GM'S warranties ?

In a way, anything could, depending on who you're dealing with. If your power windows stop working, they won't say, "oh, you have an aftermarket exhaust on there. Go fuck yourself." But a dealer MAY not cover a cat that goes bad if they determine the exhaust caused the condition. Since GM also, themselves, install Corsa exhausts, they also cover it, if they install it. You can put whatever you want on and still be fine with any warranty problems anywhere on the truck.
