Switching to Pro-chamber...
 

Asking for an opinion? Will I gain anything HP or TQ wise switching from a MAC catted H-pipe to a MAC pro-chamber I just had one installed it Damn sure sounds good :)

Is it true that O/road pipes makes 2v cars run richer?

I'm not sure about the hp and tq gains, but I heard you lose some low end tq with the prochamber. I'm glad you posted this thread cause I'm seriously considering getting a catted prochamber as well. I saw one on ebay the other day for $299.

Well I installed the O/R Pro-chamber and it sounds and feels good but my "SOTP" or buttometer isnt of the greatest accuracy! I have a friend w/a catted MAC pro-chamber and he swears by it sounds really good but I was just wondering going from the regular MAC catted H-pipe to O/R Pro-chamber? can I expect any gains?

A few HP maybe but it will be alot louder for sure :)
