Test Pipes with stock exhaust
I don't want to change the tone of my exhaust a lot, just want to make it beefier and a little louder. Would test pipes be the way to go? Any disadvantages?
I noticed my car sounds really nice when being floored while the engine isn't warmed up yet, even though I know thats bad for it, thats what I am going for. Does it sound this way because the cats are'nt warmed up yet? Would it sound like that with test pipes?

Resonated is the way to go. I have Strup non-resonated on my otherwise stock exhaust system and the rasp around 3500-4000 is pretty bad. It is definitely the sound you are looking for though, has the same throaty "growl" as stock, but almost double as loud.
The CEL will be lit on some models, you can get non-foulers that will make it go off, as well as other tricks that can easily be searched here and the web.
These do replace the catalytic converters. If you live in an emissions-strict state you will not pass inspection unless you know someone. Here in Tx they don't even look, and if they do look they only look to see if you have any (wouldn't pass if they looked, test pipes are just that - a pipe). You could hollow out the stock cat and half-*** wrap it around the test pipes to make it appear legit.
You will get the burny eyes at red lights
and the smell, it's like the fart of God- amazing.
As a final note... you should NEVER floor your car while it's still cold. Always wait for it to reach normal operating temps. Don't do that anymore. It probably sounds that way because the car may still be in open-loop vs closed? Not sure.

does adding test pipes alone increase volume by a lot that it would be noticed by cops?
also, i've heard they add about 10 whp, is this the general consensis?
final question, if I get resonated test pipes the CEL light will go off, but with O2 bung will it change the performance of the test pipes? how hard/expensive is it to install test pipes with this O2 bung?
