KO Racing ST165 2.5" Downpipe Gen 1 3SGTE
KORacing Products » Toyota Celica Alltrac » Exhaust

The KO Racing downpipe provides excellent performance combined with great fitment and ease of installation.

The downpipe features 3/8" laser-cut flanges for good sealing, 2.5" diameter (63.5mm) mandrel bent 16 gage mild steel aluminzed 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 studs for the (toyota) oxygen sensor port. The use of 2.5" pipe and large radius bends provide greatly improved flow. This results in a quicker spoolup on your turbocharger and more power throughout the RPM range.

This product includes a support bracket to eliminate concerns with cracking and comes with a 1 year warranty against defects. KO Racing designed the original downpipe support bracket that all other manufacturers have copied.

KO Racing recommends the use of a dead soft aluminum or copper reuseable gasket for the 3 bolt flange connection (like Percy's or Remflex -- you will 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.

*Note: Made to order. 2-4 weeks
