Js Racing R304 50RS SUS Exhaust Honda CR-Z 2011-2019


J's Racing

Model #R304-Z1-50RS

Shopper Award

The popular C304 SUS exhaust has evolved further. The traditional stainless steel color is coated with "titanium coating" to dramatically improve beauty and durability. The silencer structure has been revised to achieve a more refined exhaust note.

It is a stainless muffler that provides feedback and power-up through feedback from many years of exhaust development technology. The main pipe diameter is 50 and the silencer has a straight structure according to the engine characteristics, making it possible to feel the VTEC engine comfortably because it emphasizes the mid-high speed range without sacrificing the low speed range. The main pipe is made of 1.2mm SUS 304 Stainless and the weight is minimized for a better acceleration and maneuverability.
