hi just got a 07 ltr 450 and want to put a full system on. looking at 2 systems the yosh or the fatboy by DRI also with the fuel injection and the yosh system does the cherry bomb act as a power commander? or do u map the fuel and entire different. as u guys can tell i really dont have an idea and i want the best sounding and peforming exhaust i can get for my ltr 450 also any suggestions on where to buy it. living up in canada and my options are somewhat limited. sorry for the long winded topic

thx guys

 

Yoshi and DASA are the two best exhaust systems for your LTR. They are almost exactly the same on a dyno.
The cherry bomb does NOT act as a power commander. The first thing you do to your quad is get a cherry bomb (this remaps the fuel injection), remove your intake lid, and either remove the spark arrester or replace your exhaust. You will notice a HUGE difference in performance...
The power commander is an interface module so you can customize your fuel injection maps. This is only needed if you plan on other modifications. There are a few companies that make the fuel injection devices. The power commander is very popular. If you want to add a few more ponnies...get the fuelatv intake (it will add about 3 more hourse), but you will now need to remap your fuel injection.

I purchased the yoshi RS-5 and love it... either way you will not be disappointed.
