Product Description

The Spec-D N1 catback is for RSX owners who want to replace the quiet factory exhaust with a more aggressive single-exit setup. It uses 2.5-inch T304 stainless piping, a straight-through N1-style muffler, and a large 4-inch tip that gives the rear of the DC5 a much more purposeful look.

This listing includes vehicle-specific options for both the RSX Base and RSX Type-S, along with a choice between a polished tip and burnt-finish tip. The removable silencer lets you tone down the exhaust note when needed, while the direct-fit catback layout keeps installation straightforward.

Before You Order

Select the correct RSX model before adding the system to your cart. The Base and Type-S use different exhaust versions and are not interchangeable. Exhaust sound can become noticeably louder with a header, high-flow catalytic converter, or other engine modifications. Professional installation is recommended.
