Prochamber. Theres a big difference between hi-flow cats and no cats.

I couldn't agree more, as I have the Mac Prochamber with high-flow cats !

I have been pondering getting a prochamber welded in, in place of my X but keeping the hiflo cats...I think it will make the exhaust sound MUCH deeper and give another little resonator to contain resonance

I don't know which would be louder but I think the prochamber will sound better!

Hey Matt, I was wondering if the bbk's would be a direct fit with the prochamber?

I am actually debating the same thing. If I get a bonus from work then I will be getting a prochamber welded in but keeping the BBK cats.

Well, technically no...But I would just be taking to a shop where they would cut out the X pipe crossover (Leaving the HiFlo Cats) and welding in the direct fit prochamber found on the link below

Sweet, let me know what you think if you pull the trigger!!

Dude I think that would be the ultimate exhaust, BBK LT's with highflow cats to prochamber to pypes mid muffler!!!! I am thinking about getting some BBK highflow cats being as they are just metallic substrate and probably flow better than my magnaflow cats which are both metallic and ceramic...
