Which midpipe should I go with a MAC catted prochamber or a catted H pipe. Which catted H pipe is the best? Which of these would sound best with 40 series flowmasters. Thanks.

 

i flows the series 40 and the mac off road h sounds sweet with it and iv heard the off road pro chamber they both sound good,

 

Which catted H-pipe is the best?

 

I too would like to know this. I like the sound of the h pipe but which one will give the best gains?

 

pro chamber ftw

 

im going to have to agree. probably not a huge hp difference......but a difference for sure

 

red99gt,

I'm confused... I thought MAC prochambers and H-pipes ARE both 2 types of mid-pipes. If they are are not, then what is the definition of a mid-pipe? I am new to all this terminology, I am not being a smart-***. Thanks.
