Lihtsalt, juhuks, kui huvitab - väljavõte ühe entusiasti uurimistööst: ...since I was a testing kinda guy, why not punch out the stock exhaust baffles just to see what could be gained. I agreed and he began working on the stock muffler making large holes in the baffles. Once the work was complete we ran the dyno test. I was surprised to see a gain of 3.7HP and 1.3 ft lbs of torque over the PAIR and flapper mod run. The total over all gain compared to stock was 5.8HP and 3.2 ft lbs of torque and there is power gained throughout the entire RPM range! The more important thing is that significant power was gained in the more usable RPM ranges. At 6000 RPMs the gain over stock is 6.8HP and 6 ft lbs of torque. At 8000 RPMs the gain was 6.9HP and 4.5 ft lbs of torque. The max numbers were 148.04HP and 76.93 ft lbs of torque vs. stock at 142.24HP and 73.69 ft lbs of torque.

Not bad at all for free HP. The sound of the gutted stock exhaust is quite unique. It sounds pretty good and similar to that of D&D if you've ever heard one of those. A tad loud, but not screaming, and very throaty. I've learned from these tests to recommend the flapper mod and gutting the stock exhaust to anyone who owns a 1000RR and wants to eeek a little more HP out of the motor.

Eelnevalt oli ta PAIR klapi ka pimedaks teinud (juba see andis juurde). Stock summuti puurumisega pigistas pisut veel paremaks, graafik:
