I dynoed 367 bone stock with 300 miles on my 04 cobra. The guys at the shop told me i should bring it back stock after 1000. Well, we know that didn't happen.

I'm at 1500 now, and i've added the C&L kit (K&N and 90mm MAF), Bassani midlength headers and o/r X and flowmaster American thunder C/B. I'm gonna take it back to the same shop, but I wanted to know what to expect? Also, if I get rid of the flows and put up say bassani cat back or magnaflow cat back, would I get better numbers?
