    I have a unknown brand 355 exhaust and it it seems modeled after the challenge exhaust. I've seen cutaways of the OEM muffler, but not the challenge. I'd like to know if its the same inside as the challenge or maybe another aftermarket.
    Anyone have a cutaway or description of the challenge muffler?

    Hi Ken, planning to get a one-off exhaust being made in the near future, too, I´m wondering the same. As far as I know, the two bottom inlets (left&right) are routed towards two of the four exhaust tips and the central top inlet is being routed to the other two end tips. So let´s say if you would block the top inlet, only two out of 4 tips would let go exhaust fumes. No idea if the pipes within the muffler are being connected with each other? I´m sure Gothspeed of FC-fame could tell us more.

    That gives some insight, thanks.

    I got out some flash lights and mirrors and as far as I could tell, all 3 inlets in mine dump into a plenum and can come out all 4 pipes
