so ive got the Roush axleback and was debating between the Pypes O/R H or the MAC prochamber. MAC is like double the price but was wondering if its worth it

 

All I know is that I HATE the sound of the O/R H on the new 3V. The prochamber smooths out the sound a bit more and sounds more refined. I don't like it so much an O/R H will never be put on my car. But its up to you...some like the O/R H....but then again some people like sound of a fart can on a Honda[&:]

 

I had the Pypes H. Now have a Pro chamber.
Pro Chamber hands down
Cooper

 

+1 on the Prochamber

 

The prochamber is good to go. I had the pypes crap before hand and ruined the factory H-pipe in the process. Pypes' stuff is crap in terms of fitment.

 

Mac, I also have the pypes and quality and fitment were trash. Mac at least makes a good product.
