it’s an SPB fab 2 into 1 but it doesn’t have stepped headers or anything that “tunes” an exhaust. I could make up some sort of baffle but I feel like it’ll never be as good as it could be.

The thunder torque inserts worked REALLY well for torque but the flutter sound.. I couldn’t take it.

just had to bite the bullet

So anybody looking for an actual performance built 2 into 1 exhaust, look at the SP concepts big bore. I can ride my bike around at 1800 rpm if I want to now. The reversion is gone, the low rpm studder is also gone.

the muffler baffle is rifled so I’m guessing that helps with the velocity. It’s got an anti reversion chamber in the muffler and also those pro flo expansion chambers.

it sounds mean. Deep tone like a rinehart and has all the power down low and up high.

best performance mod I’ve done to the bike.

the riot was my other choice, it was such a toss up. It all came down to just looks. I knew the riot would perform, but the SPC just caught my eye.

the crash bar is original garage. I’d buy it again in a heartbeat. Looks and works great

Thats what I’m looking at seems to be just a little higher up and less worry about hooking a toe.
