I am ready to order the RB system, do you guys know if the cat delete pipe is also 2.375" I saw that Emilio is running the mazdacomp cat delete pipe and I wonder why?
I dont want a 2" bottle neck.
Thanks

Mazdacomp is 2.5" and nicely priced.
Pretty sure the RB maintains the 2 3/8" diameter.

And is a bit more expensive.

I'd grab up a Mazdacomp pipe if I were you. Especially with your boost.

I just ordered a complete RB setup with the rb cat delete pipe. $599 shipped from racing beat. I don't have turbo anymore just a vvt na swap now. Thanks for all your opinions.
