I asked them the same question while I was there and to quote the guy I spoke to ''not really, because our ramp is always in use''.
I took mine about 2 miles up the road to Austec, really nice bunch of guys there who fitted my exhaust pretty much then and there and for £45 which I thought wasn't bad at all.
Like I said mate your welcome to have a listen to mine to give you an idea of what you want
