It'll probably have to be welded in.
From what I read in the manual it is the catalytic converter. A misfire that could damage the cat.
Legally, yes.
Best way is to replace the pipe from the header back past the cat, it sold this way from most parts houses and is the fastest and easiest way to replace the cat, you can also buy the cat separate, then cut out the old one and weld in the new, but that is more work than is necessary.
Direct replacements are bolted in and some aftermarkets are welded in.
Ni, it is illegal in all 50 states.
Yes, unless the converter is clogged there is no reason to replace it.
there are 3 different cats that you have on the car..the two up front that are manifold to cat, and then the rear cat
My 2005 Jeep Wrangler X has it's engine light on which in turn failed inspection. The computer diagnosed a faulty O2 sensor on the exhaust cat converter. The cost is $240.00. The part cost anywhere from $20 to $100 depending on the vehicle.
Removing the cat is illegal in the US, also on a 97 it will cause your engine to run poorly, it needs the cat and O2 sensors to tune your engine properly. Outside the US, just cut the tubing on either side and replace with a section of 2 1/4 tubing.
If it is a diesel it is the lift pump, replace it before it takes out the injection pump. If it is a gasser replace it with a diesel. check the cat converter
"Cat back" does not include the catalytic converter.
There are no tricks. It is part of the exhaust manifold.There are no tricks. It is part of the exhaust manifold.
