Bought a welder the other day... November 21, 2004, 10:05:04 PM So I decided to make my own exhaust system for the '91 Cat.the plan is to cut the exhaust off just behind the dual cats and weld in two "glass paks" into a Y pipe and bolt up to the stock tail pipe section with no lers.Here are the pics of the Y-pipe I made. The pipe has a nice smooth transition to a single 2 1/4" outlet, which should flow better then the stock resonator, and hopefully sound better too. :evilgrin: Quote Selected
