It seems that just about everyone has a suggestion on how to get more horsepower. I was always under the impression that before you start with oxygen intake and fuel mixture....you need to begin with the exhaust system. Who out there can suggest an effecient and cost effective way to get more horsepower out of a Delorean's exhaust system without replacing it. If I am going to do this type of project I want to do it right, and work on the whole system and not just a muffler upgrade. The only thing, is that before I do anything I would love to hear of others experiences. By the way if you are sick of having a weak and embarrasing horn? I just installed a WOLO Airmite 2 dual tone air horn...and trust me no one cuts me off anymore. It install is about 30 minutes and works awesome. I got it from a local auto parts store for $25. Thanks so much. Roy Reuter
