Xpipe vs. pro-chamber
 

I have the old style collectors on my headers the 3 bolt flange and Xpipes and Pro Chambers only come two bolt style at the header. so I was wondering since i might have to get the muffler shop to weld a 3 bolt flange on my new pipe.. which one should I buy the Xpipe or ProChamber.. which one works better and performs better anyone run the chamber vs. the X? lemme know caus ei need a need H ipe mines rusted out.. only after almost 9 or so years.

What headers do you have??? I know for a fact that BBK's longtubes don't fit the Pro-Chamber. Power wise though go Pro-Chamber....It really ROCKS!!! And sounds great too.
