Axle Back Exhaust for Acura Integra (2023-2025) 1.5L

High-Flow Axle Back Exhaust for 2023-2025 Acura Integra (DE4)

What it Does: The axle-back exhaust muffler delete replaces the restrictive factory rear muffler section on the 2023-2025 Acura Integra to reduce exhaust gas restriction and deliver an aggressive, uncorked exhaust note.

The Stock Acura Integra Acoustic and Flow Restriction

From the factory, the DE4 chassis Integra utilizes a heavily baffled, multi-chambered rear muffler designed strictly for sound suppression and mass-market acoustic isolation. This restrictive OEM configuration produces parasitic backpressure behind the turbocharger and adds unnecessary dead weight behind the rear axle, completely muting the dynamic exhaust characteristics of the 1.5L turbocharged engine platform.

The Engineering Solution

This axle-back muffler delete converts the rear section into a straight-through path constructed from high-grade 304 stainless steel tubing. Mandrel-bent geometry maintains uniform inner diameter dimensions, eliminating internal turbulence and accelerating exhaust gas evacuation. Fabricated with corrosion-resistant 304 stainless steel and finished with polished exhaust tips, this kit significantly drops curb weight at the rear overhang while unleashing the true tonal quality of the L15CA powerplant. Note: Cutting of the factory piping is required for proper installation and clamp retention.
