Made great power N/A, and sounded awesome. Unfortunately only after about 6k miles, I found a HUGE crack along the welds that stretched to the first o2 sensor bung. Even in the pictures provided here the welds look horrendous. I'd be careful when buying this pipe. Currently in the process of replacement with Full-Race.

Great fit! Works amazing with n/a and f/i motors. Piping is big enough to give it power and also control noise level. Only 4 stars because you need to purchase a motor mount so that the motor flex won't damage the pipe. Recommend for any vehicle!
