Right now I'm looking at getting a Magnapack catback system and a MAC Prochamber. I am looking this way because from what I've read/heard with the magnapack system if you run a O/R X or even a catted X that there is a very prominant rasp. Also it seems as though any HP loss going to the prochamber rather than a o/r x is minimal (2-3 hp).

 

Actually from everything that I've seen or heard the Pro Chamber produces more hp than any h or x combo out there. Thats a nice sounding combo.

 

Yes, an off-road x with any Magnaflow muffler setup is going to sound like Magnapacks, it sounds absolutely badass and will frighten small children.

Prochamber is a good choice, although MAC is known for poor quality and weak welds.

 

MAC products have a reputation for terrible quality (they rust and wear easily) even though the ProChamber has a good sound. Magnaflow is a great system in terms of power, but I'm not exactly fond of the sound quality. I guess if you're looking for power and not worried about much else, then Magnaflow mufflers with an offroad x is the way to go.
