Nice find… Good install… Your stainless pipe that comes out of the engine eventually will turn brownish/rainbow from the heat. Mine did on my scorpion.( and every other pipe I’ve owned ) Take it off, wipe it down with acetone and paint it with a high temp flat black paint ....looks like this when you’re done.

How much lighter is the muffler? The stock one is a tank.

This works best after some riding...
Db killer (most left) installed
+
Perforated pipe for inlet, with plug on side to the muffler/back (it goes in reversed from pictured here)

Restriction diy rings removed(to the most right side on the pic)

This combo gives nice sound, (if someone wants more just take the rear db killer out)
And has some backpressure to maintain nice acceleration which can suffer if it is just straight pipe exhaust...

Did the Muffler come with the DB killer, or did you have to purchase it seperately?
