Tall order there...homologated pipes (street legal sound levels) are restrictive and dont produce much power. Also, quiet air filters simply wont provide enough air velocity in the venturi to make use of any other parts. We put the bigger carbs, intakes, reeds, bores and exhausts on there to increase flow as well as providing other scientific improvments to the operational function of a 2-stroke. If you would THEN add a restictive exhaust and air box to make a “sleeper”, the motor would most certainly be....asleep.


Edit: you can make a quiet build, no doubt. It can be a vast improvement over stock, sure, but you’ll get spanked by the loud dio’s easily.

I had to run a stock exhaust for a few weeks on a Corsa build because my Arrow fell apart. It was much quieter but I lost 10mph up top and take-offs were not like before. Still had loud BRAAAP from the air pod I was using and Im sure if I switched to a stock box it wouldve gotten quiet....and even slower.

Rocking stock pipe because my aarow broke to :( it's quiet for sure, but doesn't do this corsa any justice without totally retuning my cvt. Sss is hooking me up with a out of production 2fast pipe can't wait to ditch this stock one again

If its the 2fast pipe Im thinking of...it spanks the Arrow. Say goodbye to sleeper mode tho.
