I've been running a 21 in Holeshot can on my Bandit for awhile, not to loud, really (seems) to open up the top end, runs good, gets around 41.5 mpg blah blah..Last night I got bored and decide to see what kind of milage I could get with the stocker.

The configuration is the four pipes tie into a collector, then the mid pipe and can are a slip fit into that. On the stocker there's a woven wire sleeve that's a compression fit into the collector with a lip on the midpipe to hold it in place. That bolts up to a rubber mounted support and a pinch clamp, the can bolts on to there and is also bolted to a rubber mount near the rear foot peg, all nice and stress relieved, no leaks, a pretty tidy set-up. The downside is it's weight, however it looks good on there and it's quiet.

The Holeshot is basically a pipe that fits loosely into the header collector, you're supposed to use hi-temp silicone to seal the app. 1/16th gap between the wire sleeve, header and collector, then the can hangs off a strap bolted to the rear peg. The pinch clamp doesn't tighten enough to hold the mid pipe securely so all you have holding the whole thing together is the strap at the rear peg. The pipe is however a lot lighter and sounds pretty good despite the snap crackle pop from the exhaust gas leaking around the mid connection.

I guess what struck me was how much better the stock system was from an engineering point of view, it's a nice tight and secure set-up, performance wise I may have lost some flow at the high end where I hardly ever go but the low and midrange seem about the same if not a little stronger.

Holeshot is a respected stand up company with some excellent products and if I was totally out for performance they're who I'd use. However it is telling that they can't seem to get closer fits with their products. Maybe if I sprung for their header as well as the can it would tie in better but what I have is sold as a direct fit. Slathering everything with silicone sealer is fine until you actually ride the bike and the system flexs enough to break the seal.....

I just found it interesting, the first thing many people do is sh*t can the stock system off their bike and throw on an aftermarket one but in this day and age of tightening noise regulations and spendy gas and over 100 HP stock I think it's getting to be a total waste of money. Better to save your money for tires and brake pads.

You know, I don't know why I waste my money on this stuff either. For the most part I spend money on comfort items like bar risers or seats. Every once in awhile I get a bee in my bonnet and drop a couple of hundred on a slip on can, I plan on re-jetting and doing all this stuff but I never do because I remember how much I hate screwing around with carbs and jetting, I wind up running it for six months with just the can or maybe add a K&N..the bikes doesn't run any better so I go back to stock exhaust and paper air filter and go about my merry way.

Sometimes I get a couple of bucks back by selling the aftermarket can on craigslist but that's about it

No argument there, the Bandit just wailed like a banshee from 7 grand up, incredibly cool sounding and the snap crackle pop on over run sounded like an old F1 Jag or McLaren. However I just don't ride like that very much these days, I try to ride smoothly and carry my corner speed instead of point and shoot. Most of the time I'm between 4 and 6 K which is right in the torque curve and the stock pipe actually pulls better albiet more quietly.

The worst thing about it was the sloppy fit, it just irritated me every time I thought about it.
