X pipe vs H pipe

simple just plain duals sounds like a V8
H-pipes sounds like a V8 while smothing it out just a little and taking alitle drone out of the car.
X-Pipes in many cases makes your american V8 sound like a italian sportscar or just plain crap. there is few cars that actualy sound good with them.

as for power, aslong as prostock racecars dont use crosovers i will stay convinsed that the horsepowerclaims are just bogus advertising.
