Overview

Only for cars previously equipped with Dundon Street Headers.

MEGA Crack Pipe deletes valves and muffler, for the lightest, LOUDEST system. Not recommended for sensitive drivers, passengers, or neighbors!

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.
