I've been looking around on the exhaust sticky and I was wondering if anyone is running 1 7/8 headers w/ hi flow cats with the oem cat back system. With or without the stock mufflers . How does it sound and what are your impressions? I don't want to buy an aftermarket cb system if there are no gains in performance. From what I see the stock system is fine for what I need. I would consider different mufflers, I really like the way flowmasters sound with headers.
