## Description

The most torque you can buy in a catted MX5 Miata header! A great choice for street customers looking for an MX5 Miata header with converter that is 49 state legal! MX5 Miata Street Header features: -Longer, equal length runners -High-flow 5" round, 200cpi Ceramic Core Catalytic Converter -49 state legal cat (EPA and OBD2 compliant, but NOT CARB APPROVED for California, the Carsound 99659HM core is an EPA certified converter covering up-to 6.2L/6375 lbs so it easily handles the flow of our performance header while still delivering clean tailpipe emissions) -Bolt-in design for MANUAL TRANSMISSION -Bolts to RoadsterSport MX5 Midpipe...or stock MX5 midpipe. Also saves weight, factory header assembly is 15.2 pounds and this RoadsterSport MX5 Street Header with converter is just 11 pounds! Converter has two year manufacturing defect warranty (normally aspirated cars only, NOT recommended for supercharged cars), the rest is all stainless steel and has a LIFETIME warranty, even the flanges! Currently for Manual Transmission only. Also, sorry to our Australian customers but this fits Left Hand Drive only. We have included a number of extra features into our MX5 Miata Street Header which we believe customers will appreciate. We CNC machine the main flange to match the factory unit, including the bolt hole flange area thicknesses so that we are precisely replicating the factory fit to the head in terms of thread depth and space, etc. Our collector outlet is 2.5 inches. Curiously, the factory outlet is ALSO 2.5 inches and then the factory exhaust chokes down after that point. For best HIGH RPM performance customers should match our header with our midpipe and exhaust so they are running 2.5 inches of flow all the way...but our header will bolt in place of the factory header and connect perfectly to the factory midpipe for better performance from idle to redline.
