Hi dude

 

I guess the best for your Setup would be a Sip NG pipe (item code 20013C)

 

cheers

Hi dude !

 

Basically the SIP and JL Pipes has the same effect.

I recommend you to type in the search field "jl px 125" to get all pipes that are designed by JL.

 

 

cheers

thanx LaRocca for the input

I was considering a JL RZ 25040000 because it feld like this exhaust was more suitable for my cilinder timing

can anyone give some more input about the difference of both exhaust's

...........

Hi dude

 

I guess the NG is the better choice because it´s less noisy and has more tourque in the low mid and high refs.

 

The JL right Hand has more power in the mid and high refs.

 

Basically you can use both of them.

 

 

cheers

what is the SIP part number for the JL that is recommended for the Pinasco 177?
