What is I/H/E? I'm a newbie to tuning and not mechanically inclined, but I would appreciate suggestions on what to consider and how much to spend if I wanted my 04 Euro to sound really good. What's involved? Does it mean simply replacing the mufflers to something like Fujitsubo?

Also, from the discussion around headers, I think I'll give this a miss for a 10kw gain.

Thanks.
