yea , on ebay , a regular mac o/r h pipe is about $160 , and a prochamber is about $260

prochamber promotes better flow, an H is still restrictive, even when a larger than stock size, and at a certain point in the exhaust range, the exhaust stops flowing laterally between the pipes, and can cause uneven pressure.

The P/C is a box that mixes the exhaust gases in a box, and sends it back out at even pressure. It's good for a few more #s when you upgrade the rest of you're exhaust, and it sounds a hell of a lot better :P IMHO it's worth the extra dough (I have one:P)

Oh, and if you get a MAC, go to you're ford dealer and get a metal pass side collector gasket (from header to midpipe), as the MAC gasket is a POS and causes leaks :P
