What are you looking for? There are some really expensive ones out there and some that you can find really cheap. It all depends on what you want.
Basically, it comes down to resonated and non-resonated. Non-resonated are much cheaper but can have a bit of rasp to them at times. Personally, I like the way they make the exhaust a little bit louder and that's what I'm going with.
i would buy the helix ones. i had the topspeed ones from ebay and although the fittment was perfect and they looked great they made a raspy sound at high rpm. now my friend has them and it sounds the same on his car. :banghead:
