Next month I'm putting on headers and I was given the opinion of another fellow C5 member. I was originally going with ARH 1 7/8 LT headers with 3" connection pipes. His opinion was to get the whole system including the off-road xpipe to connect to my factory exhaust. I never knew the difference in sound or performance that the x pipe would make. Any thoughts? His setup on his C5 is ARH no cats, xpipe all the way to his stock muffers but not connected. He has it controlled by a noweeds system and it sounds amazing. I've seen the ARH with xpipe setup on phastek for the SS but not for the ZL1. I'm wondering if it's any different ? I will provide the link. Thank you
