Answer 1

Beside everyone telling you it is wrong....I'm sure you already know that......Check and see if there is an O2 sensor after your catalytic. If there is one don't bother on removing your catalytic because the computer will detect the difference and will show a code or try and adjust itself to run in the perameters already set in the computer. If there isn't one try it and see what kind of performance increase you get out of it.

Answer 2

This question comes up about every five minutes. The answer is the same. It's a bad idea. First of all, it's illegal. Your car will fail inspection, and that will be the end of it for you. Second, a catalytic converter offers minimal flow restriction to a stock road engine. The only thing that will increase is noise.

Removing your cats is one, a Federal offense but what ever slight gain in performance you are never going to notice the difference. I would put money on bolt ons that will give you more power than this option. There are high flow cats you can get if this is a must, but come on, its now a race car and if you are worried about gas mileage doing performance parts then you are not going in the right direction you want to go. As in you putting your foot on the gas more to enjoy that new power?, if you say you will not, you are fooling yourself and wasting our time...

Answer 4

i own a repair shop,and i wouldn't worry too much about the back pressure on this one its minimal on this one any way,but it could decrease your mileage some,usually most cars are designed to run better with these than without them,so if your getting around 20 right now its a real gamble,it could either go up or down,it may affect your engine different depending on the mileage that's on it,good luck with it,hope this helps.,,thought id add this if you have an inspection law where you live the truck will fail it if you remove the converter.

Answer 5

Suggestion: If you remove cat converter install off road chip in computer and change thermostat to cooler one. Use premium gas. If you have automatic tranny you will see a difference> torque converter lock up will change to your benefit, will have more mpg and more power. Been there and done that.

a million- U will finally end up with the examine engine mild on all the cases 2- U could have extra useful exhaust pass----> extra useful overall performance (yet not too plenty) approximately optimal u will benefit 1HP extra which dose it advise any element.... 3- the cat many times equipped with 2 O2 sensors the 1st one is formerly the CAT for Air/gasoline Ratio correction(this one facilitates u to get extra useful MPG dont get rid of it),,,, the 2nd is after the CAT which for diagnoses OBD ......

Answer 7

It's illegal. It won't improve your performance. It may make your truck sound a bit louder, but it's also going to smell like rotten eggs. Not a good trade off in my book.

Answer 8

if you can still find it used to be called a test tube but now it is illeagle to do you can have a pipe made at a muffler shop (cheapest) or buy a hi-flow from just about any speed shop but save your old one you will need it again

Answer 9

your catalytic converter has nothing to do with gas milage! it merely converts poor engine operation into "harmless" co2 and such.. so dont fear engine operation.. fear the epa

ALSO.. there is a 25,000$ if your found without a emission feature that comes standard on your vehicle

Answer 10

will actually help your mileage and performance but pls take my advice if u have it removed ( which is illegal ) put a glass pack muffler back in its place along with your other muffler
