Default How much power with a qtp cutout?

Just wondering if its worth the money for a cutout. all mods in sig plus a set of tsp ls6 heads and a fast 90/90 intake set up. i already have a pretty good flowing exhaust. Any think the magna flow cat back is very restrictive?

I think you are fine with the magnaflow but, you would see some gains with the cutout. Plus they sound mean as ****. I would go for it

The magnaflow has been proven to flow a little less then a cutout. I believe the hp difference was only 2 or 3 from back to back dynos. So I am guessing you would gain around 5 or so.

I would get the cutout more for the extra noise then hp myself.
