This is part of the reason I just have my cat delete x pipe just hanging in my garage... just not worth the hassle anymore for me.

I'll probably buy an RKP street pipe that connects to the oem cats just so I can get increased volume and still pass smog.
How much for that cat delete xpipe? I'll pick up
