Side exit exhaust
How 'bout something like this? We had to go to a side-exit exhaust on the '68 Valiant our club built as our 2008 charity raffle car last year. Didn't have room to go to rear bumper since we used the RMS Street Lynx rear suspension setup.

this is the early RMS set up like yours was.
