Is there any real big difference between a "X" or "H" pipe on a street/mild strip car? i understand there is in race applications, but does it really matter for a mild ish build? Or a complete different way...can you use a dual in/out muffler as an "X" pipe? i wanna run cherry bomb extreme mufflers and was looking at the dual in/out for two reasons...serve the purpose of a "X" pipe and i would only have to worry about sticking 1 muffler under the car... thanks for any input in advance...

 

H is an okay crossver. X is a better crossover. Merging into a single pipe is a perfect crossover.

It will just build more torque in the lower RPMs. Useful if you have a big cam or a high strung motor.

 

can you use a dual in/out meffler as a x pipe?
