Opinions needed: Match an exhaust to a lunchbox

[Soloratov]

I am going to be swapping in a lunchbox filter this winter to get some more room inside the frame for my battery and wiring. In doing this, I am seeing questions as to whether it's ok to stick with a stock exhaust.

I DON'T MIND KEEPING THE EXHAUST STOCK IF I CAN. However, if I can match up a good aftermarket exhaust without spending a fortune, I will. Full exhaust is fine, but I would prefer a slip on so I can keep my current pipes and not interfere with the oil changes.

I don't think there is any need for you to add one, but if you're planning on it now would be the time. You should be rejetting with the lunchbox, so adding them both at once and rejetting for that would be preferable to doing it 2 separate times.

There are recommended starting jet sizes available for K&N with stock exhaust: http://wiki.gstwins.com/index.php?n=Upgrades.Rejetting

I added a lunchbox a few weeks back and did a rejet, I'm really happy with the result. Bike has way better throttle response now, and I love the change in sound the lunchbox makes.

Stock pipe with lunch box is not easy to jet ... or atleast I have not done it. Slip on and K$N is easy. So is full pipe ...
Cool.

The first thing I did to my bike was the lunchbox. I didn't rejet. Then I added a Yoshi slip on. I didn't rejet.

In fact, I didn't rejet until I did a full custom exhaust with dual Yoshis.

While it is good to rejet, see how the bike is running and try adjusting the mixture screws accordingly. Then add jets to get a little more fuel as needed.

Well then, maybe I will look into investing in the Delkevic carbon slip-on. I love the look, and it's not a crazy expense. Plus it helps when others have done it...saves me re-jet fiddling.
