Back to exhaust again...what size is the stock exhaust piping on a B4q?
There seems to be some conflict (while searching) as to which catco cats to use...some say it's 2.5" others say 2.25", anyone?

Also, Miktip, you upgraded the size of the piping on your 90, correct?
If so, what did you go to, and from what point back did you go to it?
Thanks!

The size varies throughout the stock exhaust. It's 2.25" most of the way...
I don't think it ever hits 2.5" anywhere. I'm running 2.5" pipe (like miktip). I have a magnaflow y pipe after the cats, the magnaflow resonator, then a larger magnaflow in the rear. We have pretty similar setups because in the end I used his layout. I had a few other layouts before this and I definitely like the magnaflow setup the best.

That's what ETKA lists for the exhaust clamps and such...
...didn't know if that was the diameter of the pipe, or the size of the clamps though. What would be the closest to 60mm? 60mm=2.36" so a 2.25" inlet/outlet cat would be too small, so go up to a 2.5"?
