pusher pipe
My ST 60 has a MACS pipe on it. The engine is mounted (pusher style) on a Nitro Bobcat 52.
How should the pipe be modified so the exhaust will exit to the rear (toward the prop).
Do I just add an outlet to the prop side?
Do I cap off the rear of the existing pipe? I think the (new) outlet should be larger ID that the existing at the rear?
All else considered, I've seen pictures of the Weston unit and looking for Dub's version, but not yet found it.

RE: pusher pipe
Sorry for the delay !! Was away for a while.
I have a few photos of the Jett pusher version muffler in this support forum somewhere.
Modifying a standard pipe is not that straight forward unless it has an open muffler can on the aft end. Some of the MACs pipes are like that.
Dub's pusher version has the exhaust mounted on the header section so it is closer to the prop. Tuning is adjusted for the resulting internal distances and volume.
