Features & Product Details

One of the sure ways of adding more horsepower to your vehicle is adding a quality performance downpipe. With that said, RallySport Direct is proud to carry the COBB Tuning 3" Stainless Steel Downpipe. COBB combines larger piping diameter with smooth bends that reduce exhaust turbulence under throttle which helps produce more horsepower, more torque, and improves throttle response while reducing turbo lag. 

This downpipe has been fabricated from 304 stainless steel and will come with a couple of bung provisions for those of you who need to install your O2 sensor, as well as an option for a wideband gauge. Additionally, a 200-cel catalytic converter has been implemented within the design to allow this downpipe to be environmentally friendly. This is a 2-piece design that will create an aggressive tone once installed and will provide you with power and performance that you can feel. 

New hardware, gaskets, and a bracket will be provided to make this downpipe ready for installation.

I have the COBB downpipe on my car mated with the COBB exhaust and could not be happier. The sound is exactly what I wanted, and the fit and finish is perfect.
