Performance Exhaust for Husky 450SMR 2010

I bought a Husky 450SMR 2010 with twin pipe and have been very difficult to find a Perfoamce Slip On or Full System for it. People told me that I can make it single exhaust, but not sure about what can i do. HELP!

i bought a leo vince muffler for a 610 used, and had george at up-tite remove both cats and mufflers, and go with a single muffler. saved almost 10 lbs. 9,8 to b exact. engine runs way cooler. but you will need a power commander to get the most out of the bike. stock ecu runs out of room to adjust.
