I have the single exhaust system on my 94 +8, straight through side pipe from the cats back I run a modified air intake with Tornado Chip tune. As with Richard I am a two hearing aid chappy and I love the sound which I do not find intrusive, 8000 miles on Morgans Over America was a delight in my book. The high altitude winding mountain roads here in the Alpine Colorado Rockies mean lots of throaty burbling and popping coupled with great acceleration/braking. They say this is Gods country, driving all my Morgans in it makes it even more heavenly.
