2025 Neo + 85hp..

[Answ3r]

I stand corrected, that stock pipe IS really restricted. Wow

It's not "restricted", it is just NOT a tuned pipe, it's a straight exhaust like a 4 stroke.

So yes a tuned pipe will greatly increase power, but I don't believe you can get by without tuning. 25hp is a lot of fuel usually...

Just to clarify it’s Jason at SPI straightline performance that sells the neo pipe not SLP starting line products .

Anyone have an idea of the spring rate on the neo primary spring. part #417224328
