[bradders]

am I restricted in the same way with my new bike as I was the old one in having underseat exhaust, i.e. limited space around the shock? Part of me likes the idea of a single on the side, but underseat tucks it away so minor offs wont touch the can...or that';s the thinking anyway!

The monster frame dosn't lend itself to fit under seat exhaust Paul no room to get it round the swinging arm & shock.

thx chaz as I thought, will likely be similar set up to your old ones and steve masons then; light as poss can.

Did you use std headers & adapt or go larger? Also what size can - e.g. 50mm? Will probably sell the high level ones fitted to recoup some of the cost so wont be using those and need to find one, thinking an old R6 or ZXR type thing should do..

But will it pass the ACU noise Tests that are run at all MSV circuits as well as many of the others
I wonder if MTC give it a dB rating

[bradders]

just stick a baffle in cant I? Or add a load of wadding? Obviously I wouldn't want to restrict the flow too much, defeats the object!

Dont you run an R6 on yours Kev? I'd like a smaller can to make it nice and tidy but wouldn't want to run foul of the rules!

This is the look I'd love to achieve if poss, or close to, if I cant realistically go u'seat:

Rons was a monster and his underseat system looked and worked ok.

but as he said many times it was down on power

the space where the pipes go up thru the shock is very limited and if you looked at his, it had one side much larger than the other. Take a lot of dyno work, messing around and cash to sort that right unless someone got lucky

the M620 doesnt have a hoop tho and I know you can fit a 916 shock so just wondered if there was more space, not got the bike home yet so cant just go have a look, but seems those that know think not

[NBs996]

It's already got a 996 shock fitted Bradders, so that's consumed a bit of space already unless you want the standard shock on there?
Anyway, what's up with the pipes on it already?

[bradders]

yeah I know Nick, wasn't sure if it took space or made it. As is please

less weight and no chance of fouling my heels...and I want to make it 'my own'

intending it will be my track bike after racing, so think spending the money to get it right now is a worthwhile thing
