I am fortunate to have a neighbor that makes custom exhaust sytems for a living. High performance stuff, hauls a 30-foot trailer around and does hot rods and customs.
I showed him the online diagrams and he convinced me he could do a cleaner job by bending the pipes himself. He got Ansa muffler/cat from his suppliers and fabricated the rest. Sounds great and definitely improved performance. Performance probably due to the new cat, but I don't care.
$800 bucks and it is good for another 20 years.
