I want to purchase an X-pipe w/cats and a cat back exhaust. I like the Dynomax cat back, 1 beacuase of the price and 2 I like how dynomax sounds. I also was looking at getting a BBK x-pipe w/cats. I dont know too much about BBK. Do they make a good x-pipe, actually I am just wondering if it will fit correctly and pass smog. What is the big price jump in the magnaflow and bassani. Is it really worth that much more money? Also I purchased the C&L intake kit. It comes with the K&N and MAF (no inlet tube). Does anybody have this kit on their cobra? Does it fit correctly and actually do anything HPwise (havent got it yet)? Should I be nearing 300 RWHP with these things done?
