Back in the 80s early 90s I restored a few TAs and AARs. The reverse flow mufflers, hangs, tips were repoped even back then. I think Dale's Cuda Shop did the initial repop and stills carries it all.
I have a couple of F bodies, that are Volares that I want to do the side exhaust on, mainly because to do a true dual rear exit exhaust you need to move the gas tank over some, but it put the tail pipes awful close to the tank. That does not seem to cause anyone a problem, BUT......
I asked this on FEBO and got no response. (I admitted to being a drop in off FABO! LOL) Maybe NO ONE on there knows beans about the AAR??? Anyway, I wanted to know if anyone knows a source of inexpensive reverse flow mufflers,?? and for the tips to work they are connected to a curved pipe, making almost a semi circle to the tip. The repop AAR tips are maybe the best solution.
To use a regular muffler, it puts it under your seats! HOT!! no doubt. So the reverse flow puts the muffle back and the tip exits at the front of the rear wheels.
