If all you're after is a louder sound - pull that gibson setup off, get a tailpipe bent to extend the exhaust to the rear and don't run ANY muffler at all - that would be the loudest sound that you can get out of the jeep and still retain any hope of warranty (which I can't believe you're actually even remotely concerned about warranty when you were ready to hack the cats off which would certainly kill any engine warranty...) if you need examples - look at the tailpipe that the kits which locate the muffler under the passenger area, between the axles have with them - i.e. the cooltech kits.

As for programmers and cold-air inductions and warranties - most of the programmers can return the computer "back to stock" if you have a non mod-friendly dealership, and the cold-air inductions can be removed in a matter of minutes. I'd be concerned with the cold air kits letting in additional sand and dirt causing excessive engine wear over the long run.

 

o2simulator.com
he has the sims for all cars with correct plugs
DO NOT TRY AND FOOL THE FIRST O2 SENSORS THATS FOR AIR/FUEL RATIO
THE SIMS ARE FOR THE SECOND SET OF O2 SENSORS ALL THEY DO IS TELL THE ECM THAT THE PRE CATS ARE WORKING
so if you eliminate them you need the sims

 

Cold air induction? as in the k&n filters? So now they are bad? aren't they suppose to be good for the engine? And i asked the dealer if i take the cats out he said its going to void the warranty so am not doing it for sure. Am gona have to stay the way it is. So you are saying the programmer is good or bad?

 

Thats for the site, and the second you mean the ones that are between the 2 small cats?

 

So you are saying that an air filter is not good? If i install a K&N that would be bad for my jeep?

 

Depends on your driving conditions - I wouldn't use it if I were blasting down dusty roads every day - at least without a prefilter of some sort (outerwear, etc.) K&N is a brand of an oiled gauze filter - those filters are known for HIGH air flow, but at the expense of some larger particles of dust/dirt/grit getting through them when they're cleaned (look at all the K&N marketing material - they rate the filtering efficency when they're dirty, and the max airflow when they're clean...) The oiled foam filters are better at initial filtering and trapping of dust/dirt, but they tend to clog quicker and due to the reduced surface area (they're flat where the K&N and the like are pleated) need cleaning more often. They also have a little less peak airflow, but that's probably not an issue as the jeep has tons of room for a large surface area filter and the 3.8 can't breathe that heavy anyhow....

Guess what I'm saying is that there are tradeoffs to each of the CAI kits out there - and if it were me I'd be looking at one or the other depending on the conditions in which I drive... Since I do 99.9% of the driving on pavement in suburbia I'm not exposing my jeep to dusty conditions so I would choose a pleated cotton gauze type filter and call it good. If I were living down where the in-laws do and driving on dirt roads every day then I'd probably stay with a paper (stock type) filter or go with an oiled foam setup.

 

K since we have a lot of dust here, what do you recomend other than stock? i want to get the performance up? And maybe eventually a snorkel.

 

? ? ? ? ?

 

Please i would like to order a air filter and i heard if we have a lot of dust the K&N is not good? Can you please tell me what to order? Plus i want to order the programmer and we have 95octane fuel here, so will it work? and will i get the settings for more power will the programmer?
