Has anybody tried this pipe to replace the cat on their DeLorean? I was wondering if it really gives a 10 hp increase, and if this can actually be felt. In case you haven't seen it, here is the link: http://www.dmc-service.nl/Uk/Index_Uk.htm A 10 hp increase for $90 in our car, would be a great addition. Please let me know if anyone has experience with this. Thanks. -chris-
