I ordered the X pipe to compliment the Borla Pro XS mufflers I installed on 2002 Thunderbird. The power band and smoothness have increased. There is little to no interior resonance, and a smooth sound is heard as I pass by. This is the second system I have build with this part and will continue to use it on all V6 or V8 Motors.
