I want to put dual exhaust on the 68 NYer. A quote from a local guy for 2-1/4 aluminized with Dyna Max Super Turbos is $500 plus or minus a few bucks. That is bent up and installed. I found this on ebay. http://www.ebay.com/itm/1968-CHRYSL...ash=item2a5d7b4300:g:vGAAAOSwT5tWHlY9&vxp=mtr Does anyone have any experience with him? Classic Exhaust 805 Pro-Gram Pkwy Geneva, Oh 44041 When I asked about it this was his reply. It's made for all 440 engines. AP is the muffler manufacturer. I can supply stock or turbo mufflers. What do you guys think?
