Product Description

The MBRP S7607BLK is an Armor BLK center muffler bypass kit engineered as a direct, simple bolt-on upgrade for the 2014-2019 Porsche 991 GT3, GT3RS, R, and Speedster. Built from durable T304 stainless steel with a black coated finish, this kit reroutes exhaust flow around the factory center muffler, delivering a dramatic improvement in exhaust sound for any of these naturally aspirated 991-generation models.

The factory headers, catalysts, side mufflers, and sport valve system are all retained, meaning the vehicle's Sport button continues to function exactly as designed, now diverting exhaust flow to the more aggressive bypassed routing instead of through the stock side mufflers. This race profile design channels exhaust through a dual rear exit configuration for a bolder, more track-focused exhaust note.

This kit is intended for GT3, GT3RS, R, and Speedster owners looking for a significant sound upgrade without replacing the entire factory exhaust system. All mounting hardware needed for a direct installation is included, and the kit carries a one-year warranty on the coating and a three-year warranty on the exhaust components.
