im not sure but the new RSR 3" DP says it delets the cat. does that mean that the pipe comes extended with enough pipe to connect directly to the catback? basically , if i get the RSR, do i still need a cat delete pipe, or does it come basically already with a cat delete as part of it?

 

??

 

you dont need a cat delete...it basically connects from the o2 housing to the exhaust or where your stock or aftermarket catback connects!!!
