High Flow Cat, Test Pipe

[Hippofish]

Well I am having second thoughts now then. i just got my exhaust the way I want it to sound inside the car, and well if it were to get any louder, i would loose the audio system sound that I have worked on for a couple of months. I have insulated the back of the car and stopped the noisy exhaust from entering the cabin to the extent of its okay right now. However if I am only going to see a very small gain, like 2hp or less, then the extra loudness isn't worth it to me. I might just sell it then. Its a test pipe too, not a high flow cat. It just a tube with like honeycomb inside of it. Looks nice, but thats about it.

Thanks for the advice though. I will look into the throttle body. That was my next set of mods to my car, being the throttle body, and the intake manifold. I am not sure what to do about the manifold though, should I just port out the stock one, or get a totally new one?
