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.
Titanium at the rear canister does not make the whole exhaust titanium. The center-pipe construction remains a separate specification. This distinction matters when comparing cost and installed mass with a full titanium system. A burnt-looking tip should likewise be identified by its material rather than its color alone.
