Default Gutted Cat. Converter

Hi guys, on labor day I gutted my cat converter, and I was wondering if anyone knew about how many extra horses a completely clean cat gives me I haven't driven it yet because I just finished my CFI to carb conversion (along with alot of other goodies) and I haven't purchased the necessary parts to connect my cruise control, throttle cable, and TV cable yet but plan to this weekend, anyway just let me know about the cat when you get a chance. Thanks.

Doesn't really matter what you think Bodhi. I ran a 14.8 with flowmasters and a k&n. Ran a 14.6 with the gutted cat, and thats a fact.

I know it's not comparing apples to apples but I ran 13.8@103 in a 928 S4 with the only mod being the twin cats were removed. The stock stats for a 5 spd 928 were 14 to 14.5 in the 1/4.

Not only will it improve your acceleration a little, but the car will sound a lot "cleaner".
