You seem like a knowledgeable guy. I agree with all your posts, except for that comment. Whether it be a 2.3, or 2.5, you won't hear the difference with that noisy airbox/intake sound. Same goes for exhaust. A cam(for example, motor-wise) would make more influence on sound than an extra 200cc.
Thats a decent clip too.
