I had to heat up the bolts to remove them.ģ)I cut the pipe in the middle, this allowed me to remove the pipe around the frame cross members.Ĥ)Now that I had the pipe out of the car I removed the sensors, each one had two nuts hold it in place.ĥ)I cut the pipe right before and after the catsĦ) $16 of exhaust pipe and couplings from O'Reillys, I welded the straight pipe in place of the cats.ħ)Remember those rubber links? The support bracket on the old exhaust, I grinded the weld off removing it from the pipe and then welded it on the new straight pipe.Ĩ)I took the rear O2 sensor and carefully cut the protective wire cover. Separating this section of pipe from the section of pipe with the muffler. Three bolts hold it in place to the exhaust manifold, and two bolts hold it place about half way down the car. Also remove the rubber links that connects to the exhaust and frame support, get some WD40 in their.Ģ)The section of exhaust pipe with the cats and sensors can be unbolted.

You almost sound like those people who think the Deck Plate mod isn't worth it. Well until you show me a dyno test I do not believe you. Now there are people who like to say the 3.4l likes some back pressure and it actually decreases low end power. As long as it is safe to drive, I will configure my vehicle however I want. Also if you are going to talk about it being against the law for me to cut the cat out let me stop you right there. Well I'd rather buy a new gun than pay $500+ for a catalytic converter for some tree hugger none sense. I have read on this website many times about aftermarket cats failing and having to pay some serious money for a OEM cat. I have been waiting for this to happen, it gave me a reason for cutting the cat. About two months ago I got a CEL for Low Catalytic Efficiency.
