GAS High Flow Cats, Audi 3.0T Supercharged

If you're looking for our catless test pipes, they can now be found here.  ------- As many people know, tuning your supercharged 3.0T beyond just a single pulley setup can drastically shorten the life of your stock catalysts, and even cause engine damage if left alone.   After installing many poor-quality, low-cost imported test pipes, we began development on a high-quality test pipe that would last. Our test pipes (like all of our products) are manufactured from start to finish in-house in Ontario, Canada by our certified TIG welders and go through thousands of hours of torture testing on our own 3.0T development vehicles.  These high flow cats feature the same perfect fitment as our catless versions, but are 100% EPA compliant and do not require O2 spacers.   This is the solution you've been waiting for!
