FWIW, Hall Fabrication, the shop that did the engine/trans install on my car, cut the mufflers off my Kirkham-supplied pipes and used Hushpower pipes, which allegedly are less restrictive/higher flowing. Dave Brown, 4pipes, has the same mufflers on his car. Hall claims they lose less HP.
Oh and my car weighs less than yours . So neener, neener, neener.
Back to the thread.
