Have you viewed the exhaust system shootout on my site yet??? It goes over each system as they rolled off my dyno in back to back tests.

The Tangerine is a SUPER nice system and it fits and has the best quality of any system available. Unfortunately the A-1 was able to knock the Tangerine off it's crowned perch as the best conversion exhaust system for peak power during the exhaust shootout- and the A-1 is 1K bucks cheaper..
Nothing makes torque like a Tangerine, nothing makes HP like the A-1
