Will throw CEL.
cel will go off within about a week. Here in ohio we have to pass emissions every 2 years, so either pass first and then put it on. Also you could look into a hi-flow cat, this is the legal version and does about the same it just costs more.

I would recommend an EX exhaust swap. Go with a DC or Hedman shorty 4-1 header and a Random Technology high flow cat and voila! Emissions legal.
PM me if you need hook ups!

keep your stock downpipe! really, i had a test pipe and it made my car sound like bees. do you want to be a bee?
First off what kind of emissions testing do they do in GA?
Also, down the line if you plan to do bigger engine mods (Nitrous/Turbo) you're pretty much going to be forced to swap out your stock one.
Also, to the guy from Ohio, I have never heard of emissions testing in Ohio...?

i did an exhaust conversion and it worked out great. i have the random technologies cat pipe dc4-1 header and greddy evo2. so im 50 state smog legal. i couldnt tell you what the power difference was using a stock cat pipe becasue i had to do the whole conversion. but i will tell you i am very happy with the quality, the sound, and the performance of the parts i used.
