Im having 1 7/8 Dynatech Long tube headers with 3" high flow cats and the 3" Jba Competition cat back exaust installed on my car tomorrow. The cat back system comes with an H pipe I am thinking of cutting it out and putting a X pipe. What do you guys think if i put the x pipe will it change the sound by much? I was also wondering if will it take away from my torque? Here is what the system sounds like with JBA's high flow long tube headers and high flow cats and their cat back system with the h pipe.
