I placed an order for the RedStar Primary and Secondary delete about 10 days ago. I'll be keeping the cat back system. I'll post videos of before and after.

Also, JB4 was installed the same day I ordered the RedStar. On a dyno graph you can see how restrictive the stock cats are. On a Mustang Dyno, which is typically 30-40 HP less than DynoJet, the car did 658 wheel. JB4 bumped is to 749 Wheel with 91+ map. Running 93 octane.

Getting rid of the cats will allow my to run an ethanol fuel blend or MS 109 with 25+ PSI much more confidently.
