The 42 Draft VR6 high flow cat is the performance fit! The stock catalytic converter on most VR6 vehicles is a lengthy 600 cell catalyst. While failures are infrequent, replacement with a high-flow cat yields better exhaust flow & mild HP gains. The 42DD VR6 high flow cat uses a Magnaflow 200 cell metal cat in a spun stainless steel body. A CNC machined flange & TIG welded construction result in a perfect fit every time. Auto parts store replacement cats are guaranteed to 'pretty much' fit & basically 'work'. Why settle?

The 42DD VR6 high flow cat is available reduced to fit the stock sleeve clamp, or 2.5" through to fit 2.5" cat-backs. A fresh OEM gasket & replacement hardware is included with every pipe. Two oxygen sensor bungs are welded in and a plug is included for the extra. OBD1 cars use the pre-cat bung. OBD2 cars use the post-cat bung. Though based on the mk3 VR6 cat, this high flow cat fits a wide range of VWs. Check out the application guide below to choose the correct cat for your vehicle.
