You will not have issues with the Supercharger if you have test pipes. We have a lot of customers who have decided to use test pipes or been sold on them from their shop. Because of the way the valve overlap works on the VQ37 you lose some of the boost in the cylinders without the back pressure of the cats. Yes, the test pipes flow better, but because you have less boost in your cylinders, you make less power.

Hey Mark, can you show us an example of this power loss? Same car, same day, difference being with/without cats?

My car with the Stillen S/C made a little more power using Test Pipes. Best thing was less heat too!

But less boost pressure? (That's safer)

OK, all jokes aside I love this kit for my Auto Z, that's why I went this route. But let's be honest this kit is very prone to heat soak. With Hp swings from 30+hp to 30-hp real quick. That's why the Frozen Boost Intercoller is a must to help keep intake manifold temps in check! Lets take five pulls for example with Cats on and then five with Test Pipes on and you will see more consistent HP with the Test Pipes. I use the 9lb pulley and Test Pipes with my set up and see almost 10PSI. The heat the Cats give me, I gave into the Test Pipes equalling in less heat and more consistent HP even thought I might have gaven up a little PSI. At the end of the Day it's not always PSI that will get you to the finished line, but to keep the heat in check with consisted numbers that will win the race! Again at the end of the Day with less heat, the Test Pipes proved more consistent HP for my driveability.
