Alright so my car it's been on boost for the last year and a half and i've benn having a lot of trouble with the bolts on my downpipe, the biggets problem is that a regular bolt won't fit because the space between the actual pipe and the flange is not enough, and i've been using a lot of allen head bolts but the keep on coming out by themselve, if anyone has a suggestion on what to use i will apreciated

 

get a vband flange welded to your turbo and your down pipe or you can buy an adapter from ATPturbo.com from a 5 bolt or 4bolt to vband

 

thanks i think that's my last option because i already tried everything and they keep on fallin out
