yeah I agree the ARH and Kooks are probably the best available, but what are you talking about Pypes leaking? never had an issue with my Pypes leaking, and I don't even think Mac makes headers for our cars, so not sure why you'd even mention them, and BBK are not pound for pound better than Pypes, the stepped design of Pypes is better than the smaller diameter BBK's
