Best bet would be a full system of course. But, in order to get the available gains, you need a Power Commander (or some such) and all of it tuned on a chassis dyno. The pipe alone will actually decrease power as it will throw the A/F mixture a good amount leaner than it already is. With just a slipon and K&N air filter, my '09 at part throttle mid range was lean completely off the dyno chart, and to some extent, lean all across the board. IOW, barely running. Would be even worse with a full system. After the PC5 and dyno tuning, it picked up 2hp on top and 5-6hp through the midrange (where it was so lean before), and runs faaar smoother all around. Plus, lost around 12lbs by ditching the stock muffler for the Werks slipon. Whole deal was nobodies idea of cheap, but the results were worth it for me..

I would look for a cheap slip on to save weight. Delkevic comes in different styles and not bad looking, reasonably priced. I bought an M4, if I had to to it over again I would get the Delkevic.
That's basically where I would be if my bike hadn't already come with a Yoshi slip on. I like the weight savings and feedback from the engine when I'm in the canyons, but it doesn't make the bike faster at all.

I did a highway run. As I hit the entrance ramp I hit 2nd and it popped the front tire up and as I hit 3rd it was really sounding good. Of course the noise walls on the on ramps helped a lot, bouncing that sound around. City canyons! 😃

M4 specializes in bike exhaust parts for Suzuki-brand bikes. Ive got their full system in stainless steel on my Gen 3 and also had their titanium version on my old Gen 2 bike. Very happy with both. Nice note, not crazy loud. Their headers are larger diameter than stock so gives a deeper sound. Seem to last well too.

This is from the JHS racing website in the UK:
We use M4 pipes with the Supertwin machines that we build. We choose M4 because the dyno shows that no other pipe can deliver such dramatic gains from the Suzuki SFV650 engine, while offering outstanding build-quality at a competitive price.

I went w/a 300mm/14in delkevic carbon can hi-mount, 47k on the engine, stock air filter.
Not a fan of the shorty style cans, didn't want an 18 incher either.. I'm really surprised how quiet it is, I pulled the baffle before installing it, and cant imagine ever needing it.
Throaty and deep, opens up nicely when I have it pinned but aside from that it is relatively quiet IMO.

I really like it + it was only about $285. I made a carbon fiber hangar bracket for it and I'm looking into having a new mid pipe bent to tweak the angle of the can, pointing it more up and in line with the tail section angle....

I fitted a cheap Kemimoto slip on on my 99.

Mines a silver version of one of these,


Under 40 dollars. No re-jetting required. No engine power boost as such but much lighter than stock and easier to get to rear wheel for maintenance jobs.










Sounds like this,


but a bit deeper now as I've replaced the 85mm baffle with a 105mm one :)
