    yes a test pipe will give you a cel. but if you have an APR chip they have a test pipe file or you can make a defouler out of 2 14mm spark plug non-foulers. but most people on here say the best idea is a high flow cat.

    test pipe claimed gains are 10-15HP from most of the companys that make it for our cars
