For S58 drivers chasing the loudest, cleanest tone their G80/G82 can make, the MAD Single Midpipe is the answer. It replaces the restrictive factory midpipe with a single straight-through titanium pipe — no resonator holding it back — for maximum volume and a deep, unmistakable bark.

What it does

• Secondary cat delete: deletes the two resonators and two secondary catalytic converters in the stock midpipe. Your downpipe primary cats remain untouched, keeping the check engine light off.
• Unrestricted flow: the OEM dual-pipe, multi-resonator design muffles the S58's natural sound to keep things quiet. Going single-pipe clears those restrictions and lets the engine breathe and sing.
• Aggressive tone: deepest at mid-to-high RPM, with a clean top end and none of the drone or high-pitch rasp you'd expect from a louder setup.

Build

Made from high-quality titanium for a meaningful drop in weight versus the factory midpipe — better balance, better handling, better sound.
