Madmax, first a welcome.
Radios... Hmmm. Some will tell you with a bit of effort a good sound system will work ok. Others will not bother and as you say prefer to listen to the music of their intake and exhaust. For me, it's a pain.. Radio is too far away to reach comfortably while driving and I can't see the darn thing anyway so I dab around in the hope I get something or I put a cd in. Mostly though I don't bother. My 4/4 has Jenveys and a sports exhaust so I have that to keep me happy.
