I'm in the market for Highflow cats as most of you may know. But I really Don't have 500$ to spend on these things. I'm starting to really consider some test pipes due to the extream reduction in price.
I do NOT want it to sound like my friends v6 stang with rasp-masters on it.

Is there a test pipe that will give a sound close to what a High Flow Cat would. I want to keep the stock note, maybe just a little (or a lot =) deeper and or louder.

Any help would be like OMGTHX2U!
