PO had tried to run the exhaust with Glasspacks out the side in front of rear wheel. Doing this with the stock exhaust manifold is tough, and they had pipes hanging way to low to get outside the frame, and was really loud. I had local muffler shop install dual pipes and dual turbo mufflers routed inside the frame to the back and out at 45 behind the rear wheel. ($350 cash out the door) Looks really neat and has a nice sound. This brought to light the manifold leaks. I pulled the manifolds off and both sides where blown/burned out at the center two ports on the bottom. Cleaned them up, probably should have had them surfaced, but didn't. Used Mr. Gasket ultra-seal gasket, replaced all the bolts with grade 8 bolts and all seems good for now. Will check the bolts in a few days to see if need snugging up.
