Cotton 3" Ext Gate Downpipe/Precision PW46 Wastegate


The Poon Guru
Jul 1, 2008
For sale is a brand new 3" Cotton Performance External Wastegate Downpipe with a Brand New Precision PW46 Wastgate. The Downpipe has been on the car for fitment, but has never been run. It is constructed of aluminized steel. The pipe fit flawlessly with the stock frame mounts and the HR motor mounts. The wastegate pipe off of the turbo is 1.5", so it should work on heavily ported ex housings.

PW46mm External Wastegate Details

The PW46 is made from high grade, high temperature stainless steel and billet aluminum components. It features our own purpose designed Kevlar reinforced wastegate diaphragm and a 347 stainless investment cast valve body. Our investment cast valve body has a smooth internal surface, giving you better flow and more accurate boost control. Our PW46 was designed to be a direct replacement for other existing 44mm wastegate flanges, but will work best with the flange provided. The PW46 features a Nickel Chromium Alloy valve and 5 different 17-7 precipitation hardened springs. Also included are stainless steel inlet and outlet flanges with clamps. With a satin black anodized, 6061 aluminum billet wastegate cap you will have years of good looks and protection from the elements. The PW46 is generally compatible with most aftermarket manual and electronic boost controllers on the market today.

Springs are included for a multitude of pressure combinations unlike the Tial where you are locked in to a specific boost pressure unless you purchase additional springs.

The PW46 wastegate is compatible with Tials WG44 wastegate weld flange, for a trouble free bolt on replacement.

Price: $475.00 + paypal/shipping fees. Again, this is brand new and has never been run on the car.
