07 GSXR1k Short Stacks

[Wheelie]

I replaced the long stacks with 2007 GSXR-1000 short ones. Should be good for 20hp.

How you figure that? 20hp?

 

[BowDown]

How did you come up with that HP figure?

"20hp" It was a joke! Get it?

Lame I was about to steal the ones off this guys bike parked next to mine and replace them mine. He would never know

I'd be very interested to see a dyno comparision of that before and after. I did the Factory Pro stacks on my '02. Seemed like magic as it didn't lose anything down low, but really diverged at 8,000 rpm, with the only slight negative that it ran out of gas sooner. Peak horsepower numbers were the same.
FP VS
Not my bike on the graph, but the same mechanic.

it ran the same mph tonight, no change.

Schnitz has them on sale right now for $65 a set. Says they'll pick up 2-3 HP on the top end.

I like (2) of the shorties on the outside and stock centers..then add 1% more fuel to cylinders 1-4. You might need a new pipe to get 20 more HP....

I'd be very interested to seeing some back-to-back dyno comparisons! Got any GPW?

I'm all short stacks. Well 2 fac. shortys and the two long ones cut off

. I'm gonna get some velocity shorts but am not convinced it would be that big a deal
