Marlin,
I glad to see your Nova went so much faster with that system. When we did the original work on it a few years ago, I knew it would really let the cars breathe that previously only had a couple of choices of crossflow mufflers. The cool thing is it is actually relatively quiet for a muffler that passes almost 100% of the air through it that a straight pipe does. I think we achieved the best of both worlds; performance and sound control. I know it worked very well on the 400-455 Firebird we did the prototype on so I am glad it did so well on your 350.
If you email me, I can send you some photos of how we fabbed the first prototype with the PYPES front system and then fit it on the car.
