whats the deal with X pipes what do they do?

AFVETTE

In essence they smooth out the exhaust gases (or pulses) as they flow through the system. You have to remember for whatever reasons the Corvette engineers didn't install a TRUE DUAL exhaust system, they choose to "connect" both exhaust banks exhaust gases together where the H is mixing both the left and right hand pulses. In addition some claim they increase HP/TQ by a few points. The main reason most folks opt to install an X-pipe is to "tone down" some of the nasty side affects of installing ANY after market cat-back system. Namely resonance or drone and it will cut some of the popping, snapping etc on decel.

I guess you could say it "tunes" the exhaust flow slightly better than an H-pipe.

Hope this helps.
