#70272, "RE: To Gut or Not to Gut.........That is the question!!!!" In response to In response to 5
If you want a test pipe, I make kits that go for 45.00 shipped. It comes with the test pipe(2.5"), gaskets, hangers welded on, all hardware, and the special resistor for the rear o2 sensor so you dont get a CEL. I had a gutted cat for quite a while, and then made me a test pipe. Although I have a turbo, it made a good gain for me, since the inlet/outlet of the stock cat openings are 2",and I have a 2.5"/3" exhaust. If you use a round, straight through(fart can) muffler, it will get raspy with a gutted cat/test pipe, unless you put in a resonator, OR get a different style muffler.
