Does the Bonez high flow cat have the same outlet as the stock cat (i.e. 2.5" I think...)? The same question but phrased a bit differently: will it fit with my Corksport Catback?

You ever dyno tested that, or are you just pulling it out of your ***?
No, my car did not lose 25 hp. As I've said already, there was no noticeble difference, and I compared acceleration runs and there was no difference. So my butt dyno says "no difference", and my stopwatch says "no difference", so the conclusion is: NO DIFFERENCE!

maybe your stock cat wasn't crumbling




I wonder how much I'd lose if I put that piece of crap back in my TII? damn, then I'd half to put the air pump back in and all that crap.

I need to do something though, my car shoots mad flames yo!

Is it just me or does itt look like the bonez cat inlet and outlet pipes are crimped down to a smaller diameter where they meet the cat housing? It looks like it on the rx7.com website...
