No, it won't. It is however, illegal. This thread will be closed due to its content.

Whenever I had the exhaust replaced on my 93 2.5 I told them to leave the cat off and I haven't had any problems.

Just tell them it is "off-road only" vehicle. Not illegal then. Not had mine for about a year, I also have a flowmaster 40 where the cat was. Sounds great. I didn't notice any decrease in performance, but I would replace the cat with a muffler or something so you don't lose all back pressure.

Federally Mandated emissions equipment is 100% illegal to remove. The law gets a bit foggy regarding OHV's, but I would assume a vehicle originally intended for road use still has all Federal laws applying to it, whether or not it is used on the road.

Discussing the removal of your catalytic converter here is forbidden, like mentioned, don't be surprised if the thread gets locked up.

Extremely wrong information. Do you think top fuel dragsters use cats? Cats are for on road use only. Removing them is not illegal if the vehicle will be used offroad outside national or state lands like parks. It isn't "illegal activity" otherwise LED light bars, hids, no fender flares, no mudflaps, etc conversations would have to be locked as well. Law compliance is up to the OP. As far as discussions go, I don't see why this topic is any different. He isn't asking how to download movies from a torrent site.

There are plenty of people that take street cars, and turn them into drag cars and remove the cat.. And these are all NHRA approved and everything, so no it is not illegal to remove, it is illegal to drive on the road without one, but chances of being caught if you don't have smog checks are slim to none.

As stated above if you plan to just offroad 100% of the time then cut them, but if your planning on driving it on the road they are required.

Quoted from the law, no you cannot remove them ever, for any reason according to the clean air act of 1990:

Catalytic converters may not be removed
and replaced with "converter replacement pipes' by any person.
The 1990 Clean Air Act Amendments even prohibit private
individuals from installing "converter replacement pipes" on their
own vehicles. Anyone who installs such pipes would violate section
203(a)(3)(A) and (B) of the Clean Air Act (Act).
In addition to federal law, forty-five out of the fifty
States also have statutes or regulations which prohibit tampering
with the pollution control equipment on motor vehicles or driving
or selling such vehicles. Thus, vehicle owners who tamper with
their own vehicles may be subject to substantial penalties under
both federal and State law.
The only circumstances in which a person would be allowed to
remove a converter is if the vehicle is being shipped overseas to
an area where unleaded gasoline is not generally available.
(Vehicles traveling to Canada or Mexico are nnf; eligible for this
exemption.) In this instance the vehicle owner must have a
letter from the EPA specifically authorizing the converter
removal from the vehicle in question.

Question 2. can I remove a converter from a vehicle only used for "off-road" driving?
Answer 2. No. The tampering prohibition discussed in Answer
applies to this situation as well.
prohibition pertains to "motor vehicles," which are defined by
section 216(2) of the Act as "any self-propelled vehicle[s]
designed for transporting persons or property on a street or
highway." chassis configuration as meeting the applicable emissions
standards for motor vehicles manufactured in a given model year,
and it is not legal for anyone to "de-certify" a motor vehicle
for "off-road" use
.

We all know he will not only drive his Jeep off road.
We all know lying to an exhaust shop puts them on the hook if OP gets caught.
And we all know it is illegal to remove the cat converter from any emission controlled vehicle, and that it is a federal law, so all 50 states are covered.

Regardless the WF forum mods may still lock or delete this thread as this topic is too close talking about illegal activity due to too many people basically just not really knowing the actual laws.

"I have been driving for years with no cats" is a perfect example potentially suggesting its ok because you might not get caught.

Either way people that own a vehicle feel entitled to having that freedom of choice that this country gives but it's up to them either they want to do something illegal or if they just don't know enough to do the "right thing". It's up to WF forum members like us to either help that person know what he or she is doing wrong and try to help them as best of our knowledge. Or just let it be "Rules are Rules".

I say stay clean and have as much fun as you possible can. Because we only have one life and one Jeep. Or maybe two, or there, or four.

Unfortunately, they do not have that freedom of choice.

"We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness."

removing your Cat Converter (or any other emissions device) blocks others "pursuit of Happiness" by "Global Warming" and "Polluted air".... Yea, thank the tree huggers for this...

Removing the catalytic converter from any vehicle registered primarily for highway use is illegal by federal highway laws.

The Wrangler Forum will not be used for people to discuss how to break the law.

Just like with a thread that would be discussing how to obtain marijuana for recreational use or how to rob a bank, we cannot allow this content.

This thread is now closed.
