I'm thinking about getting this for my 2005 GT (Manual Trans). I read that dudes thread about X vs H pipes. The Mac Prochamber on paper sounds like it would be what i am looking for in terms of performance and sound. Does anyone own this mid-pipe and if so, how do you like it (sound, performance, etc)? Does it sound louder than stock? Please let me know if you're running it with the stock mufflers or aftermarket mufflers as well.
