Light weight and straight to the point. High flow design with minimal bends to optimize performance. Our R1-Spec single exit muffler is a great option for your 1.5L Turbo Si (FE1). Not too loud during acceleration, and subtle at constant speed cruising. You also get the burbles during normal driving during a gear change and during off throttle deceleration. 

This entire system is 2.5" from the first flange connecting to the OEM front to the inlet of the muffler canister. Mandrel bent 304 Stainless Steel piping, and straight through muffler design for improved flow. The muffler canister is offered in stainless steel with polished tip or titanium with burnt finish tip.

Brian ★★★★★

The minimal bends in the design really let my Civic Si breathe on the highway — it’s aggressive but not obnoxious during daily driving. Install was straightforward, and the weight savings are noticeable in the back end.

Lucy ★★★★★

The single exit muffler gives my Si a much cleaner look out back, and the sound is deep without being obnoxious on the highway. Weight savings are noticeable compared to the stock unit, and the minimal bends really let the turbo breathe.

Steven ★★★★★

Installed it this weekend and the single exit design really cleans up the rear end. The minimal bends make for a surprisingly smooth tone that’s noticeable but not obnoxious on the highway. Definitely wakes up the 1.5T without being too loud.
