This is an old shot of the rear on Pantera 4384.
But the exhaust system is still the same.
Headers are ceramic coated.
Rear connector pipes are 2 1/2", (63.5mm) diameter & they go over the driveshafts instead of under.
Nothing touches, has full clearance in bounce & droop.
This makes the pipe slightly longer which helps to muffle the sound a little more & I'm told by my Dyno guy, better to tune.
Stainless mufflers purchased from PI motorsports.
I Tig welded a trangular stainless flange onto the input pipe of the muffler instead of having the slip joint.
The connector pipe spigots into the muffler after the flange so there's no exhaust pressure on the gasket.
This is also done on the end of the headers.
At the rear of the mufflers I Tigged on a mount plate which in turn has a bolt on rubber insulated mount to the chassis to support the muffler weight.
