Slip-on and Emissions

Will a slip-on pipe make you fail your emissions test? My specific circumstance involves a 2009 650R with a Two Brothers slip-on in Phoenix, AZ…but any knowledge is appreciated. Anybody had any trouble?May 19, 2009 at 6:03 am #18684eternal05Participant
It all depends on the specifics of the pipe and the local laws. I know of some that do, and I know of some that don’t. A lot of people knowingly break emissions laws, and in the face of an emissions test, refit the stock equipment. I’m not sure how well that works, but it seems to be a chosen path for some.
The other thing to consider is that sometimes necessary modifications to the engine cause emissions to get worse. You won’t be jetting your Ninja 650 (it’s fuel injected), but I could see something like a power commander in conjunction with an aftermarket slip-on having adverse effects on your emissions status.May 19, 2009 at 3:04 pm #18691megaspazParticipant
In some states, it doesn’t really matter if it would pass emissions or not. Look into your local laws. Here in california, even if your aftermarket exhaust could pass emissions and wasn’t too loud, it would still be illegal if it didn’t have that EPA stamp on it.May 19, 2009 at 6:06 pm #18711
Found out that here in the desert, motorcycles are required to get their emissions tested. Now I’m trying to figure out where the cat is located on the bike. Don’t motorcycles typically have the cat inside the muffler?
Might just end up switching out the pipes for emissions…or not getting oneMay 20, 2009 at 1:50 am #18726briderdtParticipant
…a 2nd gen SV650s, the catalytic converter is inside the pipe, but before the muffler. YMMV.May 20, 2009 at 3:31 am #18729
Awesome. At least there is a glimmer of hope! Hopefully Saki has the same engineering focus as Zuki
