COBB 3 INCH DOWNPIPE: MAZDASPEED3
PRODUCT OVERVIEW
he engineering that went into the COBB 3 Downpipe
started with the CAD designed investment-cast turbine outlet, made of
304 stainless steel for enduring corrosion resistance and reduced heat
transfer to the engine bay. The shape of the outlet flange makes
optimal use of the tight confines of the MS3's engine bay, smoothly
blending turbine outlet and wastegate gases. The outlet flange is
configured with two O2 sensor bungs; one to accommodate the stock O2
sensor and another with a pre-installed plug that can be removed to
allow an aftermarket wideband O2 sensor or datalogging device with easy
engine bay access.
A custom spun metal substrate high flow catalytic converter comes next. This one piece 400 grade stainless steel cat has a much higher flow rate and longer lifespan compared to ceramic or brick style cats. It also reaches operating temperature faster than other style cats for cleaner cold-start emissions. A third O2 sensor bung is located immediately after the cat to be used by the second OEM O2 sensor.
The stainless steel flex section used in the COBB 3 Downpipe is internally lined (unlike most flex sections) and provides smoother exhaust flow and much longer lifespan for the steel braiding. The placement of this flex section in the factory location (before the first exhaust hangers) is critical in absorbing engine movement and eliminating damaging stresses that would otherwise be applied to the flange, cat, exhaust hangers and chassis. This increases the longevity of the downpipe as well as downstream exhaust components.
All tubing used in the fabrication of this downpipe is polished 304 stainless steel for increased corrosion resistance and a mirror-like finish. The 304 stainless steel hangers are cross-welded and well braced to eliminate a point of fatigue that is evident in other aftermarket downpipe designs.
The end flange uses the stock donut gasket and factory spring bolts to aid in flex, longevity and proper fitment. This provides an improved seal compared to other methods, as well as reduced noise. An additional benefit is that it makes the COBB 3 Downpipe compatible with any cat-back exhaust that mates to the factory cat section.
When researching downpipes for your MazdaSpeed3, consider COBB's intensive engineering, quality of materials, impeccable fabrication and all around versatility. The COBB 3 Downpipe is unmatched in the marketplace!
