Starting at the turbo, a CNC machined flange allows gases to merge naturally into a tight radius bend. The second bend transitions the downpipe neatly through the exhaust tunnel, separated by a stainless steel flex section. Underneath the car, a custom tabbed flange and CNC machined hanger assembly allow the downpipe to be supported by the factory hangers.  Along the way, precisely placed oxygen sensor bungs allow for factory fitment of the oxygen sensors on both FSI and TSI motors. Exiting the test pipe (in place of a catalytic converter), a long offset pipe meets an adaptor allowing precise fitment to the factory cat-back exhaust. Double layer graphite gaskets and grade 5 locking hardware keeps everything tight.

The modular nature of 42's 3" downpipe allows for changes to be made at any time without cutting or welding. On race day, the catalytic converter can be easily removed and replaced with a test pipe. Is your aftermarket cat-back exhaust too loud? The offset pipe can be replaced with a resonated pipe at any time. The stock cat-back adaptor can be replaced with a 2.5" or 3" adaptor, or a bolt-on cat-back system.
