I never did spend the $ for the side exhaust. I took what was already on the Volare RR and cut and added turn downs after the rear axle. It will get the rest of body work/paint then I will do the side exhaust..
I had several TA/AAR cars and I am familiar with their exhaust. The E body has a flater lower pat of the rocker, but it is doable with the Volare, or Duster, what ever. Cheapest way is a muffler in and out of front, AAR style bracket, and buying some decent tip deals for the exit.
