As you may have noticed from posts I have made in the past exhaust note/tone is a bit of an obsession of mine
I certainly don't own a 70's American car for the handling 
But back to the E30; one thing that bugs me is that in up-rating the exhaust system and doing some head work it sounds fantastic on full chat, if a little clinical but pottering round it's lost that classic M20 sound. You can really hear the valves through the x pipe and middle box etc. It just sounds a bit clattery and rattly.
I am a real fan of deep rasp as appose to a sort of mono sound. A few examples;
So this got me thinking does my exhaust setup with the BTB and x pipe smooth out the flow too much for rasp?
Even though it wouldn't do the power output any favors would it make a big difference to replace the x pipe with two straight pipes? So it then becomes a true dual exhaust front to rear, I suppose effectively you then hear the sound of 2 x 3 cylinder engines out the back.
Finally could the stainless silencers be replaced with more old school cherry bomb type construction for example, to dampen mechanical noise i.e. valves and give more of a period sound track,
Or am I miles off? Interested to know your thoughts.
