Hi guys

Can I check whether the original exhaust for pre-catalyser Px150 ( before 2011) can fit into the newer PX150 (2011 onwards) which comes with the original catalyser exhaust?

Thank you!

If you need to buy a new one anyway, then you'll get a free power upgrade by using an exhaust like the SIP Road 2 or similar.
Cheapest power improvement you can make.

Having just installed the SIP Road 2 on my '05 PX, there is no way in heck I would consider replacing a stock pipe with a stock pipe. The SIP pipe woke the bike up quite a bit, much more mid range power without bogging, a bit more top speed, and sounds much better without being obnoxiously loud. The mounting flanges needed a little adjustment to fit properly, but not too bad. The carb re-jet is easier than putting all your tools away.
