Exhaust Upgrades - Advice/Suggestions Needed
OK, so the next item that I am looking to do is to improve the sound, performance and potentially the look of my LS3 exhaust...
#1 Please recommend a Cat-Back - Not overly aggressive but an increase from stock...
#2 If I also change my headers will that void my warranty?
I was think of Kooks headers if it does void the warranty, but undecided on an exhaust package... I like low grumbling tones, not interested in highs.
Any help would be greatly appreciated!
