x-pipe and exit in front of rear tires?

H-Pipe vs X-Pipe.

Look at page 3.

The X-pipe will flow better than the H-pipe because the exhaust does not have to make 90 degree bends.


True...However there may be This to consider ( from the article I quoted above - post # 26 )

"The negative aspect to the X pipe design is, because of the crisscrossing of the flow stream, harmonic pulsations will develop on some systems at certain RPMs, which will be perceived as a buzzing or humming sound."




YMMV and all that....8)
