Description

This system combines a Generation 3 front section with a sidewinder megaphone muffler, designed to avoid clearance issues often associated with side-exit systems. It ensures no reduced right-hand cornering clearance or rear brake lever-to-pipe interference, and requires no fairing modifications. The stock oil cooler and lines also remain intact. Constructed from aerospace-quality, ultra-lightweight stainless steel, this full system offers a significant 58% weight savings over the OEM exhaust, totaling only 10.90 lb compared to the OEM's 26.15 lb. The system features a 20-inch megaphone muffler with a durable black ceramic coated finish and a 2.25-inch outlet. A billet, removable baffle is included, allowing for sound customization. For tuning and customization, it includes one 18mm bung for a wideband O2 sensor (with a block-off plug) and a PAIR block-off cap with instructions to reduce decel-pop. Installation includes the muffler, front section, flanges, and all necessary hardware. Brock's Performance also provides a lifetime direct support package at no additional charge. Please note that this system is NOT compatible with the OEM or aftermarket center stand.
