I'm looking to get a new set of exhausts for my SP1, but I don't know what to get. I'm going to the motorcycle live show at the NEC this month so plan on talking to Beowulf, Blueflame, Pipewerx and Scorpion to see what deals they can do, also thought about going to a16 road n race supplies if anyone has used them before? And looking at MTC exhausts. I don't want to spend more than £400 as a maximum, but less would be nice and I want the exhausts to be loud.
I've got SP Engineering exhausts at the moment (came with the bike) but I'm not entirely happy with the fit. Without the cans in the straps and the link pipe clamps as tight as I can get them, I'm still able to move the link pipes around where they meet the manifold

I just wanted to know what exhausts people had on their bikes, opinions or experiences with any of the companies I've named above, and the loudness compared to other exhaust brands.
Thanks
Matt
