My friend has an A'PEXi World Sport 2 cat-back exhaust on his RSX and it's by far the best sounding exhaust I've ever heard on any Honda/Acura (I've heard plenty to know that). And I read a lot about the Greddy EVO 2 that it is a very good system as well (just never heard it). My friend is also very happy with the power he gained with the WS2 but he said the EVO 2 will give even more power. I looked at prices and the EVO 2 is crazy expensive compared to the WS2. Any suggestions which I should go with?

i have heard everything positive about the greddy. the sound, i have heard one on a civic and it sounds really good. its not all that noisy either but when u get on it, you can hear it. they are both good systems, but id go with greddy.

Word... I <3 my World Sport 2, even though it rusted in half after six years, I couldn't risk replacing it with something else that might sound bad. As far as gains, it might not make a difference, what other mods do you have?
