I have a set of mac axlebacks and i love them but i'm still getting my friend to weld in 2 dynomax resonators to get rid of most of the drone they have.... But i am going to get a an O/R prochamber soon and i just really want to know how its going to sound inside and outside the car... Is it going to be more quiet than the stock H or Louder because i will have resonators installed? Just wanted some opinions... Thanks

anything o/r will be louder than the stock catted h pipe. but w/ the resonators and o/r prochamber, idk, might be more quiet.

take the resonators off, and go with the mac prochamber / ab combo sounds nice, deep, and loud! check out my video on the sig and midway you can hear what they sound like from the track....

I have the O/R prochamber with resonators and boomtubes and it's louder than the stock H for sure. Resonators will quiet the exhaust about 1 or 2 decibels but because you'll have the off road pipes it will still be louder than the stock H.

How easy is it to put the stock H back on when emmission times come and i need to put the stock h with cats back on??

it should just be a pop out and pop in with a few clamps.....god I hope I dont get reloacted somewhere and they check emissions....I would have to get some cats welded in.

or just swap out the prochamber and put the stock pipe with cats back in... its every 2 yrs here i think
