I was wondering if anybody took there cats off there 2.9. And in place put a straight pipe or test pipe. How much better did this improve sound and did you notice any performance gains. I would like to cause i dont want to make my truck run like crap but since the cats will need to be replaced and the quote the shop gave me was outrageous to put new cat back in. I figure it would be cheaper to just put a straight pipe in...I know it doesnt have the OB-D2 system or whatever it is called... and we dont have emissions testing here in Indiana
Have you read the sticky link at the top of the forum? If you pull youre cats, you are going to have problems. Even though you dont have emissions, why should you penalize the rest of us be spewing more crap into the air? Have you thought about the resale of a vehicle without emissions equipment? What was the quote for a new cat? Have you checked ebay? THere are high flow catalytic convertors on there for short change. What year is the ranger in question?
my ranger is a 90 and i dont have to ever worry about resale value becuae i my truck has been totaled once and now i have a salvage title. And besides i will brive this baby until the wheels fall off then i will part her out.. As far as the enivironment goes taking ur cats off on a small v6 isnt gonna cause massive global warming..hell ive heard of people passing emmisions testing with out cats on just because there truck was running very well..I feel it is more of a personal choice and I will also not have to worry about setting the fields on fire anymore...that happens alot around here.
