Mazda Exhaust Flanges
Sort by:Recommended
90-05 Miata Exhaust Flange (16173)
We offer this cast-stainless steel 2.5" ID flange for use in many custom applications.
This flange measures 12mm" thick (.5"), has 13.5mm" diameter mounting holes spaced 100mm (approx 3.93") apart (from center-to-center).
04-11 Rx8 Racing Beat Stainless Steel Exhaust Flange (16168) - NLA
Out of stockNo Longer Available, but we still make our Rx8 Steel Exhaust Flange.
Stainless Steel Engine-to-Header Flange (Renesis 13B) - This engine-to-header flange can be used to fabricate a custom exhaust system for a Renesis13B engine. Tubing This sand-cast flange incorporates the OE exhaust air injection ports which are critical for correct emissions operations. If you are utilizing this flange for the development of a racing or off-road header we offer an optional cover plate that can be used to seal the air injection port inlet.
Supplied with this header are four (4) stainless steel plugs that are needed to seal openings in this casting. (The openings are a result of the machining process required for the air injection supply configuration. These openings are normally sealed when this flange is used during the assembly of our RX-8 header.) If needed, an engine-to-header gasket is available separately.
This flange requires the use of 1.75"OD tubing material for the fabrication of the primary exhaust tubes.
