Need help picking an exhast Options

[rzanology]

Hey guys, im almost done my turbo setup...just have a few minor things to finish up on. one of which is to finish the whole 3 inch piping all the way back. I have 3inches to about half the car already, just need the rest done and also the pipe. Im not too sure which pipe to do though. I was looking at some of the pipes on ebay for the STIs and EVOs.

Here is a sti pipe

another sti pipe

here is one for supras

im not really looking for anything too loud. I know it cant be avoided, but i'd like to atlease have a nice low and deep grumble on idle and low rpm. WHat i really want is the supra sound. I notice alot of guys running the flowmaster too...how much better performing or sounding is it from obx or any of the 3 links i just posted? I also notice these pipes are really cheap...is this going to hurt my setup? will the more expensive pipes be better?
