Exhaust shopping... louder is not always better

[pdiggitydogg]

Alright its time for me to get a new exhaust and I'm having some problems with all the different kinds.

I was looking at Apex'i WS but after talking to people I decided that it hangs too low for me (car is going to be lowered) and I don't want it to scrape one bumps..like my driveway

Some guy told me about nopi e-cat having a really good price on Tsudo catback exhausts. So I checked it out, and they say the retail is over $700 and they charge $300 something. Is this exhaust worth anything? Or is it just a pipe and no muffler; kinda like the OBX system which we all know is louder than hell. If anyone has some suggestions about what kind I should get, let me know. I'm not really into spending over $600 on it.

Cheap links would be great (just no group buy center please)
