Hi guys,
My current setup about sound on my 2010 Mustang GT is Hot Rod cams, Pypes catted H-Pipe, and Flowmaster Outlaw axlebacks.
I really love this setup, however I'd like to see if I can get even better
So I am looking forward to replace H-Pipe with a MAC pro chamber.
I think this would give a special nice deep tone, but also will quiet the exhaust and I don't want it quieter, nor louder (and hope it would not tame the rough lopey idle of my cams).
So, I think I won't go with just the "cut&clamp MAC prochamber".
As my outlaw axlebacks already give the maximum volume, the only way to compensate the addition of MAC pro chamber would be to change cats for lower cell count.
My current Pypes cats are 300 cells.
So I could buy an offroad MAC prochamber and :
- leave it off-road
- weld 100 cell spun cats on the offroad legs
- weld 200 cell spun cats on the offroad legs
What option do you think would give me the same loudness with MAC pro chamber compared to my current setup ?
Has anyone experienced MAC pro chamber with Hot Rod (or Thumper or Detroit Rocker) cams ?
Are the lopes at idle still super good sounding compared with a H-pipe ? How would you describe the difference ?
