Vespa PX Stock vs SIP Road 2.0 Exhaust

[@nks80]

Sounds so much sweeter with that new exhaust on. The standard factory set up is awful & to restrictive

[@realStefanLowe]

I actually liked the original muffler sound better.

[@finneire2081]

No way can't beat that tin sound

[@Raver_DJ_Pilot]

Turn the idle up a bit, it's struggling to keep going.

Doles it just clamp,on to the exhaust pipe ?

[@chrismcternan6573]

I did the same but after about 2 days runni9ng, the revving is very erratic and the power only goes on at high revs. Did you change the spark plug to a Longer one?

[@samihasib]

Not longer, but got a colder plug.

That exactly why people ride 2 stroke ! 🤣

sound with chrome sip 2.0 is more "thin" than fat and deep with the original exhaust. Chrome SIP 2.0 contains no wool, due to production process. This leads to this specific sound. There is a saying: Who wants to be pretty also has to suffer 🫠
