The I thought one was a 260 door, but I think I worked out it wasn't (can't remember exactly now), but the bailey channel is complete toast, and I know as soon as I changed it on my 911, it made a huge difference, so I at least hope that is the bulk of it
I might have had a bit of a baffle in the exhaust just to make sure it was quiet enough for rego, that I may have only taken out today. So if that was the case, the tune may have been affected by that
