Ok, got the Q Stealth ('08 EC300) mounted up tonight and I wasn't dissappointed. The Motorcycle Industry Council has no test RPM listed for the GasGas so I used the formula in J1287; 306,000 divided by the stroke in Millimeters (72) = 4250 test RPM.
- Turbine Core 2 with about 100 miles on it -
91.8 db
- Q Stealth with a ride around the block -
85.7 db
Sound is very subdued and a little throatier. Fits well, does hit the plastic just where the can starts, but not into it real hard, is a little longer by about 3/4's of an inch. I was going to take pictures, but I noticed the white 300 earlier in this thread, so everyone knows what it looks like.
I'm pretty pleased with the reduction in sound.
Taking it up to work on our Enduro course this weekend, so I'll try and have a ride report early next week.
