supertrapp or kerker 4into1? opinions? noise/performance

[gsBert]

hi, me again.
i have a problem: i have a brand new 4:1 supertrapp headpipe, midpipe and can, and i also have the same by kerker. (both discontinued, both brand new, both pretty, both stainless)

the supertrapp is for a 89-91 gsxr1100
the kerker for a 90 gsxr750.
looks like the kerker headpipe will bolt on to my head easier but will give me slightly less ground clearance while i'll have to modify the flanges on the supertrapp to fit the exhaust bolts into my head (well, the bike's head)

i have to choose one (don't want to be the only guy on the block with an 8:2 exhaust).

which one will be the quietest?
which one will be the best match for my 1150 engine?

I'd say that the Supertrap is the way to go. You'll have to work the flanges but the baffle is tuneable so that you can get the sound and performance combo you want.
