KO Racing Downpipe
2/2/2002 Dyno Results! from Matrix Engineering.
Dyno Comparison to stock gutted Cat
Dyno Comparison to Stock full cat

$285 with extra WB o2 port

Downpipe purchase includes a support bracket. New redesigned wastegate vent for better boost control!
The KO Racing downpipe for MR2's is a must have item for owners with ct26's or ct20b's, and are interested in top performance. The downpipe features 3/8" laser-cut flanges for good sealing, 2.5" diameter (63.5mm) mandrel bent 16 gage piping, MIG welded construction, wastegate exhaust vent that allows full actuation of the wastegate, 2000 degree ceramic thermal barrier coating for corrosion resistance and thermal insulation from Finishline Coatings.
The KO Racing downpipe allows the use of the factory oxygen sensor and an extra O2 sensor port for putting a wide band O2 sensor into your exhaust for dyno tuning your fuel curve. The bung is for standard screw in type O2 sensors (M18x1.5), not the bolt on toyota type, and includes a plug. The downpipe is provided with new stainless hardware for the 3 bolt flange at the b-pipe connection, and new stainless studs for the (toyota) oxygen sensor port. The use of 2.5" pipe and large radius bends eliminates the losses in flow seen in larger pipe. This results in a quicker spoolup on your turbocharger and more power.
KO Racing recommends the use of a dead soft aluminum or copper reuseable gasket for the 3 bolt flange connection (like Percy's -- you need the 3" gasket).
*Note: this is not an emissions legal part. Use of the stock b-pipe may cause fitment issues between the exit of the downpipe, and the b-pipe flange.
See the installation instructions on the Technical Articles page.

Downpipe Support Bracket
$22 each
This bracket will help eliminate failure of downpipes due to cracking. By eliminating the motion of the end of the downpipe, the stress is transferred to the engine block rather than the welds of the downpipe. The bracket is laser cut from 1/8" thick (0.125") steel and is then bent and coated.
*Note: There is no need to order this part if you purchase a KO Racing downpipe, it is included with your purchase.
See the installation instructions on the Technical Articles Page.
