Hey guys some of you may know about my current exhaust setup. I have true duals with no cats, 18 inch glasspacks, and 18 inch tips. I am looking into getting a couple high flow cats because I get pulled over all the time for it being way too loud. It is VERY loud. What cats should I get? Any ideas? I mainly want it to be Magnaflow and it has to be high flow. Also I have been having idling problems ever since I got the exhaust. My mech. Teacher says it's because there is only 2 o2 sensors in the whole system and they are in one pipe. There are none in the other. So my other question is if I got cats and had 2 more o2 sensors drilled in, would it run better? What it does if you let it sit in park for oup to 10 minutes it will start to idle very low at like 200 rpm's and gives off a terrible odor and then gives off a really loud hissing sound from the throttle body. Help!!!!

 

well not having an o2 sensor can certainly cause it to run not so good.

putting mufflers on will help with the sound more that a cat. If its purly for sound I would not puts cats on it and put on some flowmaster series 40s. Ive got the 40s series and love the sound of it.

 

I just realized that I accidentally posted this to the wrong generation. lol
