Are the gains noticiable and does it change the sound of the exhaust?

Not sure of the exact gains you would see over a single setup, since I did mine at the same time as the headers, but the x-pipe will tame the sound down a bit. I loved the way mine sounded when I still had the cats.

to tell you the truth i cant really tell a difference other than a minor sound difference. i agree the X will tame it a bit and make it sound smoother and more "racier" if that makes sense.Originally posted by BigKID@Dec 10 2003, 10:17 AM

X-pipe sound vs H-pipe sound is hard to explain. The X changes the note up more like a high winding sound and the H is just more traditional sounding.
I read that the X is better for mid to upper RPM power and the H is better for down low.
