Another really cool unique project ExhaustWorx-at-IceTronix. A Hillman Avenger historic rally car! Be built this bespoke system all the way from the head of the block back. All stainless 304 and fabricated in house. We began with our thorough exhaust inspection, spec’d our materials and designed a stainless steel flange to start with, we then went about creating a one off manifold with a 4-2-1 design and worked our way all the way back to the rear end using mandrel bends for peak performance.
