I am currently upgrading (???) to the Banks Torque Tube Exhaust Manifold and I am using the gasket that came with the kit. I was planning on using the swivel washers for the intake and exhaust installation that I removed from the original set up, however there is difference in the intake to exhaust manifold thickness; will the swivel work?, the difference in mine is about 1/32" in most areas and up to 1/16" in a few others, I noticed that the intake flange had areas where it looks as if the washer seated in well past the flange surface. Also, are there any tips for the Dual cat Down Pipe installation, I got the pipe from OMIX ADA and it is a single pipe (with dual CAT's) to the other CAT, I have it up and in, just have to pick up some Exhaust crush seal gaskets for the pipe to header final install. I appreciate any comments.
That looks cool, sorta like 2 stroke tech? Got the expansion chamber for zero flow resistance on acceleration? How much does something like that cost? I saw two 64mm turbos on Clarksville TN Craigslist, 200 for each. I'm guessing that wouldn't work with a turbo, but for sure a pro charger. How much power gain is advertised or torque curve change?
Wait are them Cats? I guess I saw it as something else, I haven't owned a jeep with that type exhaust yet, I'm still in the 90's lol
The 99-04 California Emissions Jeeps have 2 pre-cats as well as the regular catalytic converter. So what you're looking at there is the 2 bungs for the upstream o2 sensors on the upper exhaust header, then the 2 pre-cats on the lower exhaust tubes. There will still be another o2 sensor on the downpipe, the catalytic converter, and then a downstream o2 sensor after that.
The exhaust systems were different when I lived in Germany, in fact the exhaust, head lights, body and a few other things were different spec. I think even some glass. That's probably why amazon will not ship. I would arrange to ship to you if you buy one here, but not sure if its legal. It may be cheapest to just have a muffler shop make you one, but I know in Europe that can cost a lot. Then it may have to be inspected or who knows, I'm not exactly sure what the UK spec or law is on that. Germany was really strict on even the smallest changes made to vehicles.
Hoping someone on here will have an answer for me. My 99 Cherokee was originally a Florida vehicle. So it has none of the stupid California smog stuff on it. I want to put a high flow 2.5" cat on it. Typically when a vehicle is originally sold in CA you must replace the cat with a special one. Since mine never had the CA smog stuff on it, do you know if I can get by with a non CA certified cat? Something like a Magnaflow?
I was just reading up on the extensive Mumbo jumbo lot of health and safety and emissions codes for CA (I'm here in socal too) and i didn't see anything that said you could do that, but there is always the risk that you couldn't put in a non CARB cat. I could've missed that part because it wasn't what I was looking for. I have to most likely replace my cat too because it's rattling like nobody's business (check my Instagram. I just followed you). It's hard to figure stuff like that out. It's never clearly stated, at least in CA I noticed.
I am looking for a cat back exhaust system as my stock exhaust fell off when I hit a bump (that's not the sole reason as the only thing holding it together was a custom bracket thing I made). I am looking for a reasonably priced system (around 300) that is a little more aggressive than stock but not obnoxiously loud. Thanks in advance for any suggestions.

Thanks for the reply. I was reading the same thing you were. Its like they are even unsure on what you can do as far as cats go. There are so many laws regarding cats that it is just confusing. I even read something that said that you cant replace the cat unless something is wrong with it. And you would need a shop to verify that there is an issue with it first. Guess the stock one will stay on until it has issues.
