I have a 2007 golf GTI manufacture date is 7/2006 if that plays any factor. I'd like to do a down pipe on a stock exhaust. Theres so many exhaust options for things I know nothing about. Brands and Part#s would help. User c72k is running his mouth. I just need some advice cause there's so many things. All I got is and Intake but I wanna do the downpipe boost gauge and controller and I think my DV valve is going bad. Any other suggestions. I want the stage 2 tune but I think a 3" DP is to much I'd rather go 2.5. When I get a bigger turbo then 3" would pay but 2.5 is fine. Thanks if anyone got some info
