It been a few years since my Pypes 2.5" X pipe system was installed on my 79 TA. Installing the system was a PITA for me. It would have been much easier had the car been on a lift versus 3 ton jack stands.
I too went with the crossflow transverse muffler from Pypes and the chrome splitters to give that original TA look. The pipes that run over the axle to the muffler could have been curved slightly differently and the driver's side pipe is very close to the hydraulic lines for the rear disc brakes. Also, the hangers provides were pretty much useless in their original form as the 79 TA never had the muffler mounted cross wise. As a result, I had to fabricate my own hangers and suspend them from locations so the transverse-cross flow Pro Race muffler would hang level and provide enough clearance for the exiting tailpipes to fit between the leaf springs and the body of the car so they didn't bump causing a rattle. It took a lot of swearing and adjusting to finally get the system to fit decently. Was I disappointed? Yes, but I've come to expect problems with anything that isn't original to the TA.
