I've been debating this in my head for a week or so now... I just purchased the JIC Spartan DE 2 (80mm piping) and Intense Y-Pipe (80mm piping), my question is... would it be better to get test pipes or high flow cats??? i'mthinking i need some backpressure since the car is basically going all motor, buti'm not sure about this? what do you guys think?

flame suit on for the FI guys.

 

Get yourself a nice set of resonated test pipes.

 

I assume that the “I need some back pressure” myth will live forever. Just like Elvis.

prolly will but i wanted to make sure that i'm doing the right thing and that i'm not robbing myself of off some hp.
