To all you Audi know it alls. I could use a little help.

What size is this Y pipe clamp? My stock clamps are letting valuable boost pressure past and I'm not happy with it :



Much appreciated. Thanks

Jeez, I didn't even know the car came with those annoying clamps there haha. Go to your local Home Depot or Autopart store just pick up a 2.5Inch Clamp.... Screw style. Much easier to use.

Well I bought a 2 1/2 inch clamp and its too small. When I clamp it around the pipe it just barely tights, much less get threads to tighten. So I'm thinking I will need a 3 inch clamp.

Anyone know the exact size for sure.
