Confirmed. I put a Fabspeed Maxflo on my 2001 Boxster S, and while it sounds fabulous above 4000 rpm, the drone between 2000 and 3000 is a drag. I'm thinking of doing the internal mod to my OEM muffler and putting the old system back on. Or maybe keep the Fabspeed cats and bypass pipe and graft the old muffler on. Has anybody done this?
