Anyone running this exhaust?
Any feedback?

I have a sip road 2 on one of my p2s and it runs like a dream.

I have another p2 with the sip road 2 sport and I feel that it doesn't run the same. I cant Rev the gears as much or hit the power band like I do with my other scoot.

Builds are the same. Jetting is the same. I'm actually running a 125 and a B8 plug on the good running bike and a 122 and a B7 plug on the bike in question.

Thoughts? Could air flow or air constriction due to the longer, fatter exhaust pipes on the "sport" be a variable?

Let me know. Open to your feedback and theories.

Thanks.

I used the SR2 Sport on a 177 motor and didn't notice any performance nuances, but I hadn't used a regular SR2 for reference. I soon removed the Sport due to the fact that you cannot get the wheel on/off. I went to a BGM BigBox Touring.
