[2kExploder5.0]

For an Explorer 5.0? I'm sorry if this has been a question run through the mud before but the search seemed to be too general. I already have a Thrush Welded 2 chamber muffler on (3'' inlet 3'' outlet) with a custom 3'' pipe out the rear side and it hums like a Mustang while cruising but has no chamber sound while accelerating hard. 4 cats is way too much deadining. So does anyone out there know of a company that makes one? I'm not in the habit of gutting cats due to the sound reflection bouncing around in the shells (sounds crappy).

Again, sorry if this has been asked too many times.

Thanks in advance.
