wow, with an attitude you're just gonna get flamed around here!
those 2 mufflers you listed are gonna be LOUD!! with no real performance gains... save your money and get a full cat-back... I have an Apex-i WS... its nice sound wise... really quiet... but im just finding out that its not all stainless steel, which is really pissing me off. I paid $450 for total crap!
