Seriously tho, purchase whatever you think most compliments your engine bay. There will be no noticeable HP gains from one brand to the next. Very minute (sp.) if any. I have the AMS but I probably could have had one bent at the local exhaust shop and had the same effect on performance.
BUT... the exhaust shop one wouldn't have the pretty AMS logo on it. LOL
It's a pipe for god's sakes. A pipe is a pipe is a pipe. Of all the things to nerd out on in an Evo I am always amazed how much time and debate and thought goes into it's simplest component, a friggn' pipe.
