Description
REMARK R1-Spec Cat-Back Exhaust for 2023+ Acura Integra A-Spec (DE4). Add a single-canister R1-Spec exhaust to the Integra A-Spec with a resonated stainless steel mid-pipe.
The main pipe remains 2.5-inch stainless steel. A straight-through rear canister provides the R1-Spec layout, with the selected rear material and finish distinguishing the two listings.
Compare the complete layout rather than the visible tips alone. Pipe diameter, rear mufflers, resonators, and any valve arrangement serve different purposes. A larger or differently finished outlet does not establish a measured power gain or a particular cabin sound level; choose the configuration that matches the intended vehicle use.
