Its works really good so far. The throttle response and more immediate boost is the most noticable. Water is definitely alot easier to cool than air. I just got a powder coated heat sheild for it , so that should help some as well. Although only the front half that somewht fits over the ex manifold doesnt really cause that much of a heat problem so in hoping with a heat sheild as well will improve some.Btw , nice car 242.
