1999 Chevy Astro Van with dual inlet and dual outlet flowmaster 40 series muffler.

Installed Flowmaster 40 series part # 425404 and made my own dual exhaust set -up on my Astro Van with a stock 4.3L Vortec V6 engine. Used front exhaust pipes from 1999 Chevy Express Van with 5.7L from the junkyard since the cats already removed from the salvage yard. Used the second tailpipe from 1995 Astro van while using the stock tailpipe from my Astro van and also used the stock exhaust flange for my passenger side Exhaust while the drivers side exhaust I had to modified but I happy with the results.
