I just installed the $140 FRPP xpipe on my '06 GT. The car has the Steeda/Ford Racing axle back exhuast and I'm very pleased withhow they sound together. It sort of mellowed out the tone and made it sound more refined. Still loud enough to let people know I'm around. What I hear is this is the piece from the GT500. I love it so far. Had it welded because I found a guy to do a stainless weld. Clamps were nice, kept 'em. I believe were it not for cost this piece would be stock. Why spend more?

 

Nice, I got the same x-pipe I think I paid $139.00, installed that and JBA shorties at the same time. They sound nice and the car breathes better see if you notice a surge of power when you hit 3000 rpm's
