Currently I have Mac axlebacks and I'm looking into a new mid pipe. I'm going to get hi flo cats welded into whatever mid pipe I get. Which type should I go with? I want to make it louder and I don't mind drone. Thanks

 

prochamber i have the full mac set up and it sounds awsome

 

im dying to get my mac headers n prochamber but they are on backorder for months><

 

x or h???? if you have axle back chambered mufflers, then h

 

prochambers sound nice but MAC a/b sound bad IMO with an o/r x. I have them with an o/r h pipe and its in the sweet spot, but still the prochamber sounds the best

 

I vote prochamber! i tried my macs with my catted H and didnt care for the choppy sound, i think the prochamber would sound better + youd be the first one here to have a catted prochamber and macs(atleast that i know of).

 

Well I plan on prochamber

 

Another vote for Prochamber with hi-flows. I have a procamber with hi-flow cats and magnapacks and I love the sound. I am sure the Macs with a prochamber and hi-flows will sound bad ***.

 

i had the stock cats with prochamber and macs and it sounds great so if your goin high flow cats im sure it will sounds better

 

My Prochamber is kinda quiet. But if course, I still have stock mufflers.

If I were to do it over again, I'd go H-pipe. I like the old school muscle car sound better. X-pipes generally sound higher pitched.
