let me just say i made this screamer for his car and this isnt somthing u whip up in an hour it takes time and effort 10 hours straight and not 20 bux at some exhaust place it probs cost that for the gas i used welding it customing the flange alone took 2 hours u have to allow space for the bolts to go in and for it to not hit hoses etc if u look at the mpics closely there much detail i modified and changed from the stock one and for the people that think these sound like shit let thoers have there own opinon when it hit boost the sreamer lets go and sounds fcukn mad this is sound i recomend to the people that dont have all there cash to blow on waste gates new turbo and what ever come next these are reasonibly cheap and sound mad
