Mid Pipe Comparisons?
 

Has Anybody Ever Seen A Dyno Comparison Of A Mac Prochamber And A O/r X Pipe Or O/r H Pipe? I Don't Seem To Believe That The Prochamber Would Work As Good As A X-pipe For All Out Top End Horsepower. I Had A X Pipe And Then Installed The Prochamber And The Decibels Seem So Much Lower With The Prochamber That I Believe It Must Hurt Horsepower? I Could See Where It May Produce More Torque Than A X? The Only Published Dyno Results I Have Seen Comapred A Stock H-pipe With Cats To A O/r Prochamber On A Bullit And I Wasn't To Impressed With The Results.
