Re: Exhaust replacements
I am convinced I can get a 2011 ZX10R header on the H2 SX. The tubes look to be the same size, but I will confirm. I will be trying this shortly. If this works, there will be only a little trickery to get a mid-pipe to work with the swingarm and bags. Then it can run any can I wish.

Re: Exhaust replacements
I'm with you on that.Pyrocritic wrote: ↑Sun Mar 11, 2018 6:29 pmI'm just going to wait awhile until exhaust options show up. I'm more concerned with sound, look, weight than anything.
Sound - I want sound - but I don't want noise. On a long trip I find excess noise is just plain tiring. I'd be quite happy with stock dB levels. I don't need to announce my arrival. Sound - now that's different. A more throaty or fuller sound is music to my ears. I'll gladly listen to my engine sing.
Look - yeah, the stock can isn't pretty. But some of the photos I've seen posted around look kinda shabby too. Of course, look is down to personal taste but a neat setup will appeal to many people's taste. Any replacement should look as if it belongs on my new pride and joy.
Weight - a worthy consideration. Should be one of the top priorities but I wouldn't just fit a bean can just because it's lightweight.
More Power - I'll take it if it's there but not a decider for me. Bike has plenty of power to begin with. An ECU flash will add more at a reasonable cost. Modern exhausts are pretty good in terms of power so an aftermarket exhaust doesn't seem like good bhp/$ to me. That doesn't mean I wouldn't buy one but I wouldn't compromise sound, looks, weight or cost just to pick up a few extra bhp of bragging rights.
My views.

It's amazing how fast you can go when you take your time.
Re: Exhaust replacements
I did pull the stock canister to see if the exhaust valve was doing anything at full throttle for a run and it picked up 4 hp, not really much percentage wise

8" stainless steel 2.25" OD pipe from my local speed shop. and a 2.25" inlet Micron can from Ebay. Done until something better comes along. Cost? $150 to my door.

Re: Exhaust replacements
Is that 8" pipe straight, or curve in it? If curved, could you guess the angle?
