This Yonaka Motorsports catback exhaust system is made of fully polished stainless steel, with 2.5" OD mandrel bended piping, and a 3.5" tip. The muffler produces a quiet, clean, deep hum, without that irritating mid range raspy sound.
Direct bolt-on fit to OEM. All installation hardware is included, minus o2 bung.
Note: The 1996-1997 Mazda Miata models have an extra o2 sensor in the mid pipe section. This catback does not include the bung for installation of the o2 sensor. It will physically fit but will require a minor modification for the addition of the bung to accommodate the o2 sensor. The bung can be purchased from your local parts supplier or mechanic for a minimal cost. Your mechanic will drill a hole and weld on the bung for installation of the o2 sensor. For additional information please consult your local muffler shop or mechanic prior to purchasing this catback.
Disclaimer: Recommended for off-road use only. Check with your local ministry of transportation in regards to exhaust regulations.
