Depending on how much rasp would determine the resonator size. I'd say a 14in body would do it if there is a little rasp. I can only say the 30in body I have is doing a great job at combatting the rasp. When I rev it past 5K there is slight rasp, but who sits around and revs their car all day? I have no problem with slight rasp on a standstill rev because there is none while driving.

 

Richie, are you going with a magnaflow cat like the hfc 3rd cat? can I send you my pcd's to add a cat to them?

 

We are going with a different approach. I am sure you can sell the PCDs.

 

I want!!!
