I'm interested in replacing the exhaust system on my 1800ES with something a little bigger, something that breathes better (partly in preparation for whatever future mods I may take on.) I'm open to suggestion as to size, single tip vs. dual, etc. I would like to get away from the skinny S-curved pipes that came stock with the car, though.<p>Can anyone suggest a good configuration? Ideally, something that preserves the metallic <I>blat-blat-blat</I> sound, and maybe gives a little more bass but without getting louder. <p>The great thing is, I don't have to worry about emissions regulations, so no cat!
