Show original supplier description
The Fujitsubo RM-01A exhaust system is engineered for competitive driving, including gymkhana and dirt trial events, prioritizing weight reduction and performance. This model achieves remarkable weight savings through revised silencer capacity, thinner main pipe material, and the adoption of lightweight brackets and flanges, all while ensuring structural integrity. The system features a 76.3φ pipe diameter and a φ99 straight tailtip with a hole, designed to optimize exhaust flow. Performance gains are evident, with an increase in peak power from 210.7kw (286.6ps) to 217.3kw (295.5ps) and peak torque from 382.2 N･m to 399.8 N･m. The overall weight of the Fujitsubo muffler is 11.3kg, compared to the standard 15.2kg, representing a substantial reduction. This RM-01A exhaust is specifically designed for the Subaru Impreza WRX (GDA), Impreza Sports Wagon (GGA), Impreza WRX STi (GDB), and Impreza Sports Wagon STi (GGB) models with specific 'A' and 'B' applied models, covering years from August 2000 to October 2002 (H12.8～H14.10) and October 2000 to October 2002 (H12.10～H14.10) for STi variants. For models from November 2002 to June 2004 (H14.11～H16.6), the rear silencer upper floor shield will require bending加工 (processing). Important fitment notes include: it is compatible with GDB Spec C models and sedan models equipped with the genuine rear underspoiler. However, it is NOT compatible with sports wagon models that have the genuine rear underspoiler installed.
