R500 Exhaust

[WKD]

Need a new exhaust for the R500. Got pinged at Brands at 106.7db the other week. Seem to have narrowed it down to BTB or Raceco. BTB claim 100db +/- which is attractive as the limit for the GP track is 101db but I don't know what the Raceco does. Not sure how much power I'm going to loose either.

Anyone got any advice?

You'll lose no power with a Raceco. With airbox and 7.25 Raceco which could do with repacking, mine measures a regular 102db at "ahem" 5,500 RPM

another vote for Raceco - with one of their neat titanium jobs & a reverie airbox system, my R500 was quiet enough to do Bedford which has to be one of the strictest tracks for noise.

That's what I've got - I'm going to have to repack it I think....

Yep, most recently at Snetterton last week - first time I've driven there - bloody quick!

Thank you very much guys. Sounds unanimous.

How can anyone guarantee any given noise reduction? Will depend very much on the engine. If in doubt though, get the biggest one possible. I gained a little bit of power when fitting mine, but I'm sure that depends too.
