Was thinking of getting either a catted X pipe or a MAC prochamber for my 98 GT. I'malready getting the MAC cat back exhaust.Any recomendations? What's better performance and sound wise?

 

It's a toss up, it's all about your preference. Prochamber definitely sounds good with the Mac catback though.

 

i agree with onyx

 

Prochamber for a deeper rumble. xshould be louder. For a deep rumble v8, prochamber. Performance = x.

 

actually if anything the prochamber will outflow an X pipe. there is no reason to buy a midpipe for power, there is very little difference between a prochamber, an x pipe, adn an h pipe as far as power.

for a deep rumble buy an H pipe. louder idle and in lower rpm. x pipe is louder in the higher rpms and extremely raspy, prochamber sounds more like an X pipe but doesnt have the rasp. its a deeper sounding X pipe.

 

Did you say the Prochamber doesn't have rasp?

 

nothing to the extent of an X pipe, atleast in my opinion. x pipe is obnoxious IMO, prochamber is more tame.
