The STM Stainless Steel Axle-Back Exhaust System for the 2006-2013 IS250/IS350 AWD and RWD models connects directly to your factory y-pipe/cat for a perfect, USA-made fit and finish.
A full stainless steel, 2.5" mandrel-bent construction ensures a lasting quality backed by the STM Lifetime Warranty. This axle-back completely removes the back mufflers and opens up the exhaust flow for the performance and sound this car was missing. Sound clips are below.
The STM Exhaust utilizes your existing exhaust hanger locations and includes all clamps and hardware for a clean installation.
