Staintune

[PowerDubs_imp]

Guth: I'll put it this way. I want to change the exhaust because I like the sound. but considering the astronomical insane cost of changing the exhaust, i *also* want it to improve performance, because if i can't have both, it's really hard to justify it being worth such an insane amount of money. Changing just the sound seems like a superficial waste of money to me. even a gain of 10 or more HP would be cool. That said, just changing the pipes is not all i'm going to do when I do my performance changes next year. so far i'm settled on changing the exhaust, having an ECU flash to maximize performance, and making sure the FI system is adjusted to work in concert with the new exhaust. Also, i'm going to change a sprocket and move the power band a bit. of course, a mechanic is going to be doing all this, i have no idea what i'm talking about. all that combined should provide me with a significant and noticable gain in overall throttle response.

So, i'm beginning to gather that if I get a Staintune and I want to increase performance, I'd have to go buy headers separately? Anybody got any suggestions?

Nowhere near that much from a muffler swap. At most only a few hp.

Yea- that is pretty much the standard on any bike, car, etc- open the intake and exhaust, give it a little more fuel to match. The problem on this bike is simply that none of those items are the bottleneck. So changing them does very little currently until the cork is removed. (cams)

Changing gearing does not change the shape of the power band. The dyno curve would remain the same.

Gearing is simply tq multiplication. A larger rear sprocket, or smaller front is the cheapest & quickest way to literally put more power to the rear wheel- but the way the power is delivered through the engine range does not change.

At this point- gearing is the greater impactful way to get more acceleration. You will notice it more- and the bike will be measurably faster from a gearing change than it will from any air filter, headers, muffler, ecu flash.

Since you are mentioning Staintune, I'm assuming you have a std bike. The common header I see for that is Arrow.

My only concern with removing the cat is how does the bike sound afterward? I know on many cars removing the cats sounds horrible- raspy, tinny.. bleh.
