SM510 catalytic converter removal

Husqvarna makes a non-cat dual exhaust for them. See the following link. Some people put dual exhausts on models that came with single exhaust and some people put single exhaust on models that came with dual exhaust.

The cheapest, easiest option is to put in the power-up parts and leave the exhaust alone. It should run well with no other mods and maybe the cats will eventually plug up, maybe not. Some people say to wait until the warranty expires and some say to do it right away. See what the dealer says and if no issue, put the power up parts on ASAP.

The spark arrestors only come on USA and Canada models as far as I know. That was true for '08 anyway. You can see them from the outlet end since they're only an inch or two long. All the '09 models come with cat elements. Can be removed from TE, not from SMR (without cutting and welding).

will the te510 fmf pipes fit the sm510 2009? hangers are the same etc...? thanks guys

Here's a great thread to answer that question.
