I just saw a cut-away diagram of the stock muffler and I must say, it looks like it should offer good exhaust flow with very little restriction. Is there any credible information about how it compares with aftermarket systems in mid-range (where we ride most of the time on the street)? Now I am tempted to get one to try on my M2 to see how it performs in "real world" riding. I am not concerned with high RPM dyno numbers but I do appreciate a nice strong mid-range and I value torque above maximum horsepower. My M2 has a 40 mm Mikuni and a Race pipe and can with a stock ECM. Runs great. Any experience to share? Do you think it might work out for daily street use? Thanks, Dave | ||

Dave, I have a stock muffler on my 95 S2 and a race can on my 96 S2T. Both motors and intake are stock. The stock exhaust is great around town and provides for a lot of low end torque. The race exhaust is a lot better on the highway. Seat of the pants tells me the 95 w/stock exhaust is a lot quicker. It sure is smooth and not loud at all. In fact, my 95 S2 is not as loud as my stock XB12R. Sorry, nothing scientific but I really like the performance of the stocker on the S2... The design of that muffler is really something special and i think it was mentioned in the 25 Year book by Court and Dave. I will have to check. Frank | ||

The off idle and top end performance from my X1 are about the same with the stocker and the daytona boss I have. The mid range on the stock can makes my bike feel like it's pulling a trailer though! You have to actually downshift on the highway to pass someone fast with the stocker. With the loud pipe, I just crank the throttle and it hops above 80 eagerly in fifth.. | ||

just put a stock m2 exhaust on my S1, worlds of difference between the v and h ss2r and borla, both of the later added low end torque and passability on the highway, but the neighbors love the stocker, overall, not too much of a difference but both aftermarket exhausts offered better all around performance, the borla being the best. | ||

What "i" did to my OEM Muffler was to put a OUTLET on the right rear ... Saved the BIG $$$.$$ by not buying the aftermarket systems ... | ||

What's the weight savings between stock and aftermarket? It's been almost nine years since I changed over and IIRC there's a big difference. | ||

LaFayette, you got pictures of the modification? Kyrocket, the stock exhaust does weigh considerably more than the borla (c/f can) and a bit more than the ss2r (metal can) | ||

I had to switch the V&H SS2R with OEM in my '00X1 for a week or so while waiting for ECMSPY cable and the difference in off-idle and low-mid RPM acceleration was definitely noticeable. I also had to "fatten up" my fuel maps to better feed the bike with the V&H. I don't ride the bike aggressively so I can't comment on WOT or top end performance. The most scientific comparison that I have seen was a dyno chart for a stock bike which showed a sizable dip in torque curve between 2500 and 3500 RPM. The dip was totally smoothed out with an aftermarket exhaust. The problem is I don't remember which exhaust... | ||

The thing seems to be that any aftermarket exhaust would smooth that out. They put that resonant damping in there on purpose to get by the EPA. That's why punching a hole on the right rear of the stocker allows it to have more midrange. | ||

How much does the stock exhaust and, while I'm at it, how much does the breadbox weight? I'm betting that my CF ham can and CF slip on exhaust save 15 lbs. or more over the stock components. That is enough reason for me, even if the power gain is zero, to have these components on my bike. | ||
| Dave_02_1200 |
The main reason for my interest in trying a stock exhaust is that "neighbor relations" might be improved if I put a quieter exhaust on one of the two Buells for early AM departures and around-the-neighborhood errands. I just don't want to mess up the way it runs. | ||

Some aftermarket exhausts are louder than others...If I remember correctly D&D is the loudest. My V&H is just right for my taste. Loud enough to get the attention of the cars drivers and not too loud to disturb most neighbors. | ||

When I last changed out my SuperTrapp IDS, I weighed it on a bathroom scale, and while I don't remember the actual number, I do distinctly recall it weighed about 2 pounds less than the stock muffler. I have gained about 20 pounds myself this last year, so it seems insignificant compared to that. The V&H is lighter, but I never weighed one. There's a Dyno chart showing the IDS compared to stock, in the forum Show us the Power. There's not that much difference: http://www.badweatherbikers.com/buell/messages/3842/11112.html?1100449364 (Message edited by jayvee on January 09, 2009) |
