03-07 S300/S400 Over/Under

Create your own over/under style compound kit. All tubing and flanges are made from high quality US sourced 304 stainless steel, this is much stronger and more corrosion resistant than mild steel and aluminum. Complete kits are built on actual trucks meaning no room for error or mis-alignment. You wont find this anywhere else! Black sleeved stainless/nylon braided oil feed & drain lines with AN style fittings provide a leak-free oiling system that are rated to 5000psi. Your engine will only see around 100psi when cold. V-banded intercooler tubing eliminates silicone coupler failure, our design is much more reliable than others which means you'll keep the boost where its supposed to be, feeding the engine! Turbo compressor covers will also be v-banded  to elimintate all silcone connections. V-banded downpipe make for easy install that can be done with one person and easily adjustable to align the exhaust.
