Valvetronic Designs SHUTO™ Valved Exhaust for Honda Civic FL5 / FK8 Type R / Acura Integra Type S

Overview

Honda engineered the FL5 & FK8 Type R and Integra Type S around one goal: the most engaging hot hatch and sport compact ever built. The shared K20C1 2.0T delivers 315hp, revs past 6,500 RPM, and comes wrapped in a track-tuned platform that sets the class benchmark. But the factory exhaust keeps that engine's true character bottled up.

The Valvetronic Designs SHUTO™ Valved Cat-Back Exhaust System connects to the OEM mid-pipe and runs 2.5 inches from inlet to tip, flowing through our valved mufflers and exiting through brushed single-wall Valvetronic tips. An electronic valve system with included controller gives you full, on-demand sound control — aggressive or refined, at the push of a button.

Why It Works

• 2.5" Mandrel-Bent Tubing: Reduces back pressure and sharpens throttle response throughout the rev range.
• Electronic Valves: Rapid actuation for seamless, instantaneous sound transitions.
• Precision TIG Welds: Every joint built for performance, track use, and long-term durability.

Sound & Control

• Valves Closed: Near-OEM volume — refined, socially acceptable, and daily-driver friendly.
• Valves Open: Raw, high-revving K20 character from idle to redline, with the crackles and pops that make the Type R legendary.
• Controller: Plug-and-play electronic controller for complete on-demand sound management.

Construction & Options

• Material: Brushed T304 stainless steel.
• Craftsmanship: Precision TIG welds; smooth, high-flow mandrel routing.
• Tips: Brushed single-wall Valvetronic tips.

Installation Notes
