I too would be curious if an aftermarket catted dp would have any benefit with the stock exhaust..Hi,
Right now I am running a Cobb Stage 2 OTS map with a cpe intercooler and cold air intake. What kind of benefit (hp wise, overall heat mgt. etc.) would a catted down pipe with stock exhaust have?
Thanks!
Any different sound?Yep, ran one for two years. No dyno results, but spools a lot faster and butt dyno says it makes more power. (CPE Catted DP w/ stock catback)
