Holy sheat Batman!
Fired up my ST today, first time in months, still just 293 miles on the clock.
DIY DP and Exhaust
3" DP with 5" 100 cell metal core cat, 3" outlet.
3" exhaust with the least bends, angles, etc, I know of.
5" diameter round resonator
3" in and out straight through Borla SS packed race muffler.
I thought it might actually be a bit to loud for me but it is quieter than stock!
I built for no drone, great flow, low weight as possible, best flow, etc.....I did not expect this to be so quiet but there are 4 "mufflers" in the system.
Turbo
Cat
Resonator
Muffler
I built a muffler delete pipe for the rack, V band so easy to change, I will test it and might have to run it all the time just so I can hear something at least!
