Got them in Ceramic...'bout 5yrs or so...changed a gasket about 2 yrs ago...never have changed a collector gasket...ceramic is holdin' up pretty ok and I do drive gravel quite a bit...no complaints for the price...worst luck I ever had was with Hedmans...wouldn't waste money on those again...I like Hookers also, just a little more cash...I bought the Flowtechs after reading an article in Peterson's where they said some pretty good stuff about them as far as getting to plugs, fitment, etc....I'd buy 'em again....the next step up I would consider would be the Hooker Pro Comps w/ Jet Hot Ceramic coating....Ask 20 people and you'll prolly get 20 different opinions....buy what you can afford, I seriously doubt you can tell the diference in the seat of your pants... /forums/images/graemlins/waytogo.gif
