Why 3 stars? upkeep is why.

Don't get me wrong here i absolutely love this exhaust and it has a huge boost in power, like crazy power. BUT the company says this "every 6-8 hours of ride time you must re-pack the exhaust" so i am like ok no biggy right? well i looked it up and the price is a $100 per re-packing.... and that is really costly if you follow their rules and re-pack after each moto or after every 6 hours of ride time which is why i give it 3 stars or else it would have 5 stars. It does improve the bikes power and it makes it sound alot better but i absolutely dislike the cost of upkeep and say what you will about me being a cheepo but that's too much cost for repacking and upkeeping on it.... other than that i highly suggest getting the exhaust!

A: I'm sorry for the error on our website. I confirmed with Yoshimura that the RS-9D Complete Dual Exhaust With Stainless Header comes with the AMA Pro Sound Inserts installed and included at no extra charge.
Because there are too many variables outside of the control of the manufacturer, Yoshimura does not offer any statement or claim regarding the decibel (dB) rating.
With the AMA Pro Sound Inserts installed, the system maintains the AMA Regulation sound levels. An additional spark arrestor reduces noise only slightly.

A: Normally when installing a slip-on only minor changes to the air/fuel ratio are needed, if any at all. If your bike is currently running properly, likely you will not have to make any changes after installing this slip-on. I would recommend installing the exhaust and riding the machine to see how it is running then decide if you need an purchase an aftermarket EFI tuner .

A: You will want to remap after installing the exhaust on the 2013 CRf450r. Even without installing an exhaust the CRF450r can benefit greatly from a tune. You have options of purchasing a piggyback tuner such as a Power Commander or you can even send out your stock ecu to a performance company for re-mapping.
