I used SPACESHIP parts to build the ULTIMATE exhaust

I wanted to build a unique exhaust for my new daily driver, so I grabbed some parts for a spaceship! They call it a polyphonic harmonizer, and its really just a tuned resonator of sorts, but in order to get this exhaust dialed in it took me FIVE DIFFERENT VERSIONS! still the coolest sounding exhaust I've built this year... https://youtu.be/PVwWLpxCWiw Grab a cold air intake for your truck from RealTruck https://imp.i128439.net/xJ9JE1 3.5" Polyphonic Harmonizer (the spaceship exhaust) https://summitracing.pxf.io/DWVW02 Flowmaster Flow FX Cat back exhaust https://imp.i128439.net/jRWRXP Flowmaster Pro Series Muffler https://summitracing.pxf.io/QYOYPo
