Since its "universal" and will give a strait pipe effect and keep me from haveing to crawl under the car and manualy open one. Yeah the point I was just wondering if anyone hear has ever used one or know someone that has one and what your opinions about them are.
there was a post about this just a few days ago.. digital pyro was thinking about using one and he was told that the cast iron ones are insanley hard to weldup and the moveable ones dont close right all the time.. so they leak and make noise.. the ones that have a plug and wing nuts should work realy good.. but u gotta get under the car and take off the nuts to run striaght pipe
