Exhause advice for C5
Personally, i dont like Borla. Never been into their systems. Mufflex, and Corsa is what i would recommend. And for intake do you mean like K&N air filter, or actual intake? B/c K&N or i believe its called the Blackwing are the two most popular. And an LS6 intake would be ok, but would be a better setup with other engine mods, imo. Hope he enjoys the C5.
