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)

And has some backpressure to maintain nice acceleration which can suffer if it is just straight pipe exhaust...
