Morning All

Just bought a CBF500

Downpipes are rusty as heck and the exhaust is scraped up badly, the rest of the bike is clean though.

Been looking around, seeing lot's of different shapes and sounds, but I'm wondering what one would choose if looking to increase BHP as much as possible.

This machine currently outputs about 56 BHP, would 60+ be achievable with a new exhaust system?

Been trying to look for power spec's on them but have come up with no results.

Thanks, Scoot

Are you taking it track racing? How often do you run at Wide Open Throttle at the peak of the power curve? Thinking

Are you really after peak power (torque x revs) or more roll on torque? At what point in the rev range?

What's your budget for re-jetting and doing dyno runs?

InB4 if you want a more powerful bike, buy a more powerful bike, it's the best use of your money. Wink

If it were me, i would just get that, cheap and good enough quality. I doubt massive power gains would be possible with a more expensive system as its not the most powerful of bikes anyway.

I'm not really too fussed, it's just the current exhaust system could do with a replacement and I was wondering if there are any particular brands to go for...

I've only had a day to ride it so far, just coming from an IL4 400cc I'm really enjoying that low down torque grunt, so I suppose more of that stuff would be great. The bike will spend nearly all of it's life inside London, so it should benefit more.

I'm soo used to low revs, I have been riding in the 3-5K margin, but occasionally running it through the gear all the way up-to 10k but there's never any real reason to rev it that hard, it pull's well enough lower down and there's not much more to be had higher up.

What would you go for Roger? (apart from another bike of course....)

Thanks, Scoot

Yeah, seems nice for the money, would improve the look of the bike two-fold.
