ISR Performance EP Dual Axle Back Exhaust - 2013-2020 Lexus IS 250/300/350 RWD

The ISR Performance EP Dual Axle-Back Exhaust is a straight-pipe rear muffler delete for the 2013-2020 Lexus IS 250, IS 300, and IS 350 in rear-wheel-drive configuration. Replaces both rear mufflers with straight-pipe sections capped by dual burnt-blue rolled tips, delivering an aggressive exhaust tone throughout the RPM range. The loud option for owners who want the rear mufflers gone entirely.

What It Does

This is a muffler delete, not a muffler replacement. Both factory rear mufflers come out and get replaced with straight-pipe sections that exit through dual burnt-blue rolled tips. The result is significantly louder than any muffled axle-back, with an aggressive note across the entire RPM range and no drone management because there are no mufflers to drone in the first place. Best for track-focused builds or owners who want maximum aggression and don't care about volume.

Critical Fitment Notes

RWD MODELS ONLY. Will NOT fit AWD models. The AWD Lexus IS uses different rear exhaust routing.

Early-generation bumper modification required. The dual-tip layout is wider than the factory single-tip-per-side openings on early third-gen IS bumpers (round tip openings). If your IS has round tip openings, cutting/elongating the bumper to fit the wider dual tips is required. Late-model and F-Sport bumpers (oval tip openings) fit with no modification.
