Santa brought me a new set of headers from PI Motorsports. They look awesome. Big 4 into 1 with 2.5" collector. They won't fit up to my current Ansa mufflers so I have not installed them yet.
Currently I have a 72 Pre-L Pantera. Going by pictures in this parts page (from PIM) I have 4th series headers and 3rd series mufflers. Despite the 2.25" flange on the Ansa mufflers the actual pipe is much smaller, probably under 2" dia.
So here's the question. Does the GTS+GT5 muffler have a larger inlet pipe and flange than the earlier mufflers (series 1,2,3,4)? Is it fixed or loose to rotate? They are stupid expensive.
The only other mufflers I can find are dual glasspacks by Precision Performance and some stainless mufflers by Circuit Werks. Then there's the option of buying a muffler and having someone custom fab inlet pipes.
Anybody with big bore headers out there? What are you running for exhaust and how did you mate them up? Pictures if possible.
