"3" Downpipe with Divorced Wastegate (DDP)
This specially designed full 3" downpipe utilizes a seperate pipe for the wastegate exhaust that vents to the atmosphere, making for less turbulence and higher flow for more power gains. Dyno results have shown gains of 29 whp over a standard 3 inch downpipe setup. Warning: Running the wastegate straight to the atmosphere makes your car LOUD at full boost.
As with all my downpipes, this eliminates the stock heavy restrictive turbo elbow. It has 3/8" thick flanges and bolts to the CT26 turbo and up to the stock or replacement main cat. This downpipe will increase throttle response and the turbo will spool much quicker than stock and will make 13psi at 2600-2800 rpm, and keeps pulling hard up to redline. Made from mandrel bent aluminized steel and coated with VHT high temp paint. Includes a new gasket and bolts for the catylic converter flange. Uses the stock O2 sensor and heat shield.
*NOTE The pictures shown here are with the optional polished ceramic coating*
*Please allow 3-4 weeks for build time and delivery.
Price $385"
