Street Posted May 19, 2009 Author Report Share Posted May 19, 2009 just take a stock cat and gut the inside. They can't tell from the outside if you do it right. i might just leave the 1st cat alone but the 2nd one near the rear...there is no sensor near it just the one at the front, im thinkin about taking it off and gutting it to c how it sounds with the muffler i just got put on today...

Ipod Posted May 19, 2009 Report Share Posted May 19, 2009 I feel you man I just finished my Automotive training, about a year ago, right now I am finishing getting the rest of my ASE certifications, so I can be ASE master certified. yeah its cool.. might just get my degree in automotive technology too since only i got 2 more class to take for that degree.. nicee.. how many ASE cert do you have right now? People do it by having a car that isn't OBD-II, or converting the engine management so it is pre-OBD-II.Also: If you want to avoid hassle at visual inspections, just take a stock cat and gut the inside. They can't tell from the outside if you do it right. yes but you are not gonna be able to convert an OBD II car to OBD II.. i mean its possible to do but if the smog tech is smart enough, it would not pass.. and those that dont know, OBD II was issue by the government for the 1996 and newer vehicles... and yes.. you can gut the inside cat, but when running the smog test, its not hard to tell if your cat is gutted or not... by gutting the cat just save you hassle from the Po-Po for illegally modding your exhaust system..

Ipod Posted May 19, 2009 Report Share Posted May 19, 2009 (edited) i might just leave the 1st cat alone but the 2nd one near the rear...there is no sensor near it just the one at the front, im thinkin about taking it off and gutting it to c how it sounds with the muffler i just got put on today... if im not mistaken, i think your referring to the resonator... you can take that off.. that was put on by the factory to reduce the noise from the exhaust system.. btw.. what kinda car is it?

white4d96 Posted May 19, 2009 Report Share Posted May 19, 2009 Yeah, sniffer test won't tell lies. In some cases, certain counties within your state may not require a test. My brother has an Integra that he converted to OBD-I to turbocharge it, and he registered it for use in a county where his buddy has a cabin (in WI you can register a car to your address, then you pick the county where it will be used most) and they don't require tests. And Street, if you only have one O2 sensor before the first cat, it shouldn't be a problem. Just don't gut or remove a cat that has an O2 after it. Quote Too many projects, too little time...

Easier to gut it or just have a piece of pipe welding in its place edit: its a 99 Chrysler Cirrus 6cyl 2.5l Edited May 19, 2009 by Street Quote My Babies 97 2.5 Avenger, 92 5.0 Fox, 97 2.0 Turbo GST Eclipse, 00 2.0 Jetta, 06 GSXR 600, 98 CBR 600, 01 GSXF 600, 93 CBR 900RR Wilwoods dont slow your car down, they slow the earth down under your car...remember that next time you slam your brakes, you may spill my drink.

Easier to gut it or just have a piece of pipe welding in its placeedit: its a 99 Chrysler Cirrus 6cyl 2.5l im not an expert either, but im just going by what i am taught and experienced.. to be honest, i havent look inside a resonator before so i cant say.. why dont you just remove it and do whole new pipping from cat back? the muffler will be a little louder without it.. i suggest you keep the resonator just in case its gets a little too loud for your own liking..
