Exclamation need a high flow cat to replace presilencer

So i have the racingbeat REV II Complete Exhaust... which has a presilencer and two mufflers... thats it.... well i went to get it inspected and this year the guy notices... so what i need is a highflow cat to put in the place of the presilencer so i can get it inspected... then i can pull it off... so any place i can get a highflow thats pretty long... under $130... and would not rob mme of power if i decide to keep it???

I've been thinking of just getting a 'stock' exhaust for emmissions time. Make it an easy bolt on type exhaust, or just making the cat area interchangable.

Buy the Bonez cat and keep it in your garage.

I built mine from a JC Whitney cat. Just buy the biggest one you can afford.

My local Midas actually welded it up and installed it for me. Their only screw-up was that they cut the air injection port from my presilencer instead of from the junk stock cat that was sitting in the hatch.

Never had a cat related emissions problem since then.

They do have turbo cats, scroll down.

Actually I may be moving out to CA, I was thinking of getting the Bonez performace cat and premanently replacing the presilencer in my RB turbo-back. Only thing is I'm not sure whether I have the early or late RB turbo back, and I'm not sure how to tell the difference.
