This is a 2.5" inlet and outlet diesel CAT for use in any TDI. It provides better flow than the stock CAT while reducing particulates and exhaust smell. This CAT is ideal for use with our 2.5" downpipe. It's possible to use this CAT with the downpipe and no muffler (where local laws allow) and maintain a reasonable exhaust noise level.

For use with pre-2007 vehicles only! Not for cars equipped with Diesel Particulate Filters! This converter is not CARB certified for use in California.
