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.
