Overview
Get the best sounding, most powerful exhaust for your GT4RS. No compromises. Over 3 years in development and 11 Prototypes to get it right.
Great Sound, and Great Power without drone!
We have spent the last TWO YEARS building, testing, iterating and improving this design. Now it's finally ready.
Using the latest technology in additive manufacturing, made from 347SS 3D-printed internals, this design keeps the “valve-open” pathways as short as possible, but still merges the waveforms of both banks for the great flat six symphony we're all wanting.
Nice and quiet when you want it to be, the right kind of flat six scream when you ask for it!
Choice of tips: keep your OEM Weissach Tips, Dundon Polished "935-style" tips, Dundon Polished "Megaphone-style" tips in 3D-printed 316 Stainless Steel!
Makes 30whp at 8400rpm and 37lbft at 4800rpm in additional power over the car stock!
