ntg44, have you noticed a change in rasp after a few hundred miles? Mine no longer rasp, just the usual upshift "fart" if I catch it at a certain rpm range when the exhaust valves do their thing. I didn't think it would change, but I guess coating the interior exhaust pipes with soot after a few hundred miles did it's thing in a good way.
Hey spool, I found at a track day with my single exit exhaust that it would have a little rasp at the beginning of a session when going full throttle onto the track, but after going full throttle out of the first corner that there was none. Same thing with dyno pulls.
