Sure did, I was deaf after our blat down the A5, but had a huge grin on my face, 3 old long stroke triples on full throttle, all with race cansI think the alloy can gives the bike that edgy sound. You should have been sat behind me down the A5!!!!! I think Mot and Dave_P got a little of that exhaust note ringing through their lids at some stage.
The 3 into 1 sounds a bit more raspy/metallic at the top end, its got a different sound than the standard downpipes, sounds great
Will also keep my eyes open for a Sebring for you mate, but it might be better to get some custom pipes made up anyway, as you said
