Très satisfait
Beau pipe, Facile à installer, Plus épais et robuste que le pipe d'origine, Courbe de puissance semblable et peut-être meilleur que le pipe d'origine.

Fit And Finish is 100% as described
Bought this pipe along with FMF Turbine silencer to replace 2010 yz125 factory pipe and silencer Fits like a glove, and the added sound and performance are exactly what I expected.

I waited one week for the local dealership to find a distributor for an FMF pipe for an older KTM. FortNine had one in stock and I got it within a few days. Product fitment was perfect. I'll be coming back.

Questions
Might be a stupid question but, is this price for 2 pipes or 1?
This is a vehicle specific item. If you enter the year, make and model of your vehicle on the product page, you will be able to order the vehicle specific part for your bike, if there is one suitable for your application

Would i be able to try the pipe and send it back if it doesn't do what i want?.. I have a pro circuit platinum pipe with a r-304 shorty silencer but would like more bottom end and get into the power band quicker
Unfortunately, we cannot accept returns on items that have already been installed unless it is a for a warranty issue.
