X pipe vs H pipe

1Fast340 said

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.

Pretty subjective statements. I've owned/driven all three; the exhaust on my '72 Scamp is X piped and it sounds nothing like an Italian sportscar, nor does it sound trashy/same goes for my wife's '04 Mustang GT. Out of the probably hundreds of American V8 powered machines I've been around with X-pipes, none of them sounded anything like crap. The order of sound (deals with degrees of travel between pulses) is still the same regardless of what exhaust system you have installed. And if it sounds like crap, then the mufflers or tuning of the car are more to blame than the pipes themselves.

My '84 Mustang did have an H-pipe setup and it sounded kinda raspy at certain RPMs/throttle settings, but that was much more to do with the mufflers than the pipes, otherwise, I liked it.

The hp claims are what they are-I won't say numbers aren't tortured, but prostock cars don't typically run a full exhaust anyway, so naturally, there aren't any gains when an X pipe is compared to an open header or short collector setup.

X pipe systems can be harder to route due to space requirements, and more than likely will add cost to your exhaust compared to straight or h-pipes.

In short, go with what you want...
