    Hey guys, I went to the muffler shop and talked to the guy about it. Since there are no emission checks in Illinois he is going to just take the cats off and replace with straight pipe. There was even a town cop there why we were talkin bout it. He didnt care What are these dummy boxes you guys talk about? I dont understand what you mean. Do you think with the flowmaster system the car will sound good? He is only chargin me $45 for what he's doin. He said he could gut the passenger side cat but he wouldnt do the drivers side since its not straight. But he said it would sound better just with a straight pipe. What do you guys think?

        How about this....

        How many miles are on your car? The catalylic converters are covered for 8 years/80,000 miles!!! If you are under warranty, you can just have some new ones put on for free. Also, new cats wont harm your exhaust flow as much as your old ones.
