Hey Carter,
I have been thinking about the APR bi-pipe too.

I think you are mistaken about the APR bi-pipe. My
understanding is that it does replace the TBB with one piece
cast aluminium. The replacement for the TBB is integrated
into the down pipes (not really the correct name, not sure
what they are actually called) Where as the MTM solution is
just a heavy duty TBB replacement.

Maybe if somene has it installed they could take some
pictures. I didnt see any pics on the APR site.

Wouldn't an MTM
>Y-hose upgrade be the more logical thing to do?
