Good for you.

Your argument is still based on two wrongs making a right. You are still wrong.

And now your contradicting yourself...you say a "good cat will probably flow as good as a testpipe, but it will still be restrictive." What????

We can do this all day man, Im not trying to be an ass, but youre saying that it doesnt matter about a test pipe being bad for the environment, everyone uses em so why not use them? Not a kosher argument.

Besides the fact that if a cop ever pulls you over and happens to want to get down on his knees and check your fartcan exhaust system...depending on your state youre looking at an impounded car and thousands in fines.
