Sorry, Just went to Rick's website and they are developing chambered exhaust for 4th gens. They are working with Braxxton systems. You can call them (Braxxton) direct to find out if they have something you can use. Their Phone # is 770-592-6262. Let me know how you make out.
For all your exhaust needs call Gardner Exhaust in Rhinebeck NY. They sell chambered along with traditional systems. This is the place that many hard core restoration shops turn to, they are the best in the business, ask for Tom.. http://www.gardnerexhaust.com/
