WTF did I buy exhaust for?

You might be dumping a considerable amount of weight as well. I don't know how the 821 exhaust is configured, but most slip ons save decent weight.  

Exactly 7lbs on my Monster 1100 EVO between the stock can and the CF Termi slipon.

An almost negligible difference actually.  If you dropped that much weight in the wheels you would notice it.  Dropping it from the exhaust, you won't notice it.

My stock 1100 EVO cans were 12.5 pounds

My new SC Project GP-M2 weighs in at 2.87.

That's a pretty big savings off just one piece. I would expect most to come in around that weight savings. That definitely helps with the handling of the bike.

Only my old S2R800, I switched from an arrow full sytem to boomtubes and immediately noticed more neutral handling during turns. The power wasnt there but the handling more than made up for it.

In my opinion, its not the weight but rather that the weight hangs off the bike like it does. If it was more centralized like the 1199's I dont think it would make that much of a difference.

12.5 pounds combined or for a single can??

[ducatiz]

Weight.

Typical aftermarket exhaust is half to 2/3 the weight of the factory turds.

12.5 pounds combined or for a single can??

On my evo they are one piece

STOCK Weight in Pounds (NOTE: Scale is only accurate to .5 and it rounds down so its probably between 12.5 and 13)



GP-M2 Exhaust in Pounds 2.87 lbs measured (Used a more accurate scale so weight is as listed)

Sound.  Looks.  Weight.

Stock = 3.1kg

SC Project = 1.4kg


That is 3.4kg saving (i.e. more than half the weight)
* that was my old bike, the new one has Termi's which I didn't put on so didn't weigh

Damn, EVO cans are heavy! I can't remember off the top of my head how much one of my M796 cans where but I know the Mivvs where 6-8 pounds lighter combined.

Thats definitely something I'd think you'd feel, especially since the exhaust is on one side.

Only have to check out bikeboy.org to see the performance improvemt from changing pipes. Some models more than others.
The DP exhaust kit (and ecu), gave 6 more hp for a HM1100 (J D Hord website).

Remember, HP/Nm figures are now given in % since it is a more stable figure . . . Plus also remember that these depend also on many external factors as temp, altitude, fuel quality, "state of tune" of bike . . .

Many manufa turers are chamging to % instead of "hard" HP/Nm numbers . . .

[koko64]

 That seems a smart way to do it to cover the variables.

I was quoting from Hord's dyno test of stock show room Hypers with and without the kit. They were DS models. Not bad, 80 to 86hp,  that was the full 2 into 1 system and DP ecu.
