Hello Chris! I'm a little confused, I thought a stock Delorean had approx. 135 hp? Is there a difference between hp and bhp? Or what else is the reason for this difference? ciao, Ralf Philipp Germany > The results are:- > > Stock system...............120 BHP ( only) > > new system with twin cats 135 BHP > > New system without cats 142 BHP > P.S. are there any sound samples available of the new exhaust system? :-)
