TKO Exhaust System - $650

The TKO Exhaust System is the premier exhaust for MR2 Turbos, with the highest published dyno gains of any exhaust on an otherwise stock MR2 Turbo. The exhaust features 3/8" laser-cut flanges for good sealing, 2.5" diameter (63.5mm) mandrel bent 16 gage piping, MIG welded construction, and high temperature paint. The Exhaust utilizes dual 6" (louder), 7" (quieter), or 4" (you may want earplugs with this exhaust) diameter round stainless Magnaflow Mufflers and 4" rolled edge stainless angle cut tips. The exhaust has a deep tone that is actually quieter than the Greddy Power Extreme (TM) with the 7" mufflers, while having an aggressive sporty sound when you are done fooling around. All hardware and Percy's gaskets are included with the exhaust. More pictures can be seen in the photo gallery.

Specs:
34 lbs. (stock is 43)
3" into dual 2.5" mandrel bent aluminized pipe
dual 4" stainless double wall tips
dual stainless 4", 6" or 7" mufflers

Also available in a 3" version for $800

KO Racing Downpipe - $285

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.

KORacing 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.

Downpipe Bracket - $22

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 powdercoated with a gloss black powdercoat.

*Note: There is no need to order this part if you purchase a KORacing downpipe, it is included with your purchase.
