Improve the exhaust flow and acoustic character of your Porsche Cayenne 958 S (4.8L V8, Non-Turbo) with this Milltek Sport Secondary Cat Bypass System. Replacing the factory secondary catalytic converters with straight-through 304L stainless steel bypass pipes, this system reduces exhaust restriction — delivering improved flow and a more characterful V8 exhaust note, particularly at higher engine speeds.
For off-road or track use in jurisdictions where secondary cat removal is permitted. A straightforward bolt-on replacement. Made in the UK by Milltek Sport.
Fitment: Porsche Cayenne 958 S (4.8L V8, Non-Turbo)
