Technical details
We spent TWO YEARS building, testing, iterating and improving this design. Using the latest technology in additive manufacturing, the Mega Crack Pipe is made with 347SS 3D-printed internals that keep the pathways as short as possible while still merging the waveforms of both banks for the great flat six symphony we're all wanting.
Choice of tips: keep your OEM tips, Dundon polished "935-style" tips, or Dundon polished "Megaphone-style" tips in 3D-printed 316 stainless steel.
Makes 32whp at 8000rpm and 37lbft at 4500rpm over stock with our Street Headers.
