Looks nice. What mufflers do you have? That looks like it will be seriously loud.

It's a Kooks race series bullet muffler.
It's loud but not overbearing in my opinion. It's quiter than the dumped super turbos I had before.

Boyd Butler - a.k.a. Dr. Gas - has done a lot of research, to optimize his "X" design. There are others that are probably good, but I personally will spend a bit extra to get the one I trust the most - Dr. Gas.

I was originally leaning towards Dr. Gas but I believe , if I'm not mistaken, they are constructed from aluminumized steel.
I wanted the whole system, from the collectors to tips, to be 304 SS so Pypes was the only option for the mid section.

So to answer a previous question, to my knowledge, No the other X's on the market are not the same. |

I installed a 3" Pypes with their 3" SS mufflers. It's side exhaust, and loud, but it's a Road Race car. Some tracks have db limits but about any mufflers gets you under.
Biggest issue I had was the exhaust note (pitch) is so much higher than with the H pipe and 2-1/2" that I had on it, I'd think I was in the wrong gear and had to really watch the tach much closer. I almost went with Spin Tech SS oval, but their stuff gets pricey.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
