Re: exhaust what do you think?
Total unprofessional speculation here, but, it would seem the exhaust gases and associated sound waves now have two avenues of escape. Neither muffler will be under the same pressure or work load of a single stock muffler. My guess would be a decrease in emitted sound waves. Also as previously noted with two exits available the back pressure should be decreased roughly two fold. It would be out of my range of knowledge to speculate on performance changes. I too am very curious about your results.
