The system includes a straight-through, multi-core muffler and a removable silencer for adjustable sound levels.

Show original supplier description
The Spec-D N1 catback exhaust system is engineered to deliver a more aggressive exhaust note and a distinctive visual upgrade for the 2002-2006 Acura RSX Base and Type-S models. Constructed from durable T304 stainless steel, the system features mandrel-bent 2.5-inch piping and CNC-machined flanges for optimal flow and fitment. This catback exhaust system utilizes a straight-through and multi-core muffler design, paired with a substantial 4-inch single exhaust tip. Buyers can choose between a classic polished stainless steel finish or a striking blue burnt titanium-style finish for the tip. A removable silencer is included, allowing users to moderate the exhaust volume as desired. Fitment is specific to the Acura RSX Base (2002-2006, 2.0L K20A3 L4 DOHC engine) and the Acura RSX Type-S (2002-2006, 2.0L K20A2 / K20Z1 L4 DOHC engine). It is crucial to select the correct version as the Base and Type-S exhaust variants are not interchangeable. Exhaust sound can become noticeably louder when paired with other modifications such as headers or high-flow catalytic converters. Professional installation is recommended, and some user reports indicate potential fitment adjustments may be needed, with one user noting the muffler was angled significantly to one side and required slight modification to avoid contact with the bumper. Another user experienced a rattling issue with the silencer insert, which was resolved by tightening the mounting bolts.
