ok everyone...who here has heard of SMS headers??? they're a north carolina based company...the reason i'm asking about this is because my friend tells me they're the best...he has the headers on his car...his car is a 89 civic hybrid that runs a 12.32 second all motor setup so i think he knows what he's talking about...he said something about resonators being put into the headers...said it allows for more horsepower because extra air doesn't get sucked back in through the exhaust system while letting off the throttle...don't call me crazy =) this is the first time i've ever heard of something like this...i was just wondering if you guys have ever heard of it...he said they custom make every header and they cost around 800 dollars a set...does anyone have some information on this or can provide some feedback??? thanks!
