Installing a DC ceramic header on my stockish EM1. I cant get the header to fit over the head exhaust studs simultaneously with the exhaust hanger studs (just behind the oil pan). Is there a trick to making it fit? I didn't think I'd have to remove the studs in the head.

 

Loosen or remove the two 12mm exhaust hangar bolts, up by the oil filter

 

If it is a 2 piece header install the header first then the y pipe if it is a 1 piece the do as tlarimaer said.

 

It's a 1 piecer. Tlarimer's suggestion worked. Thanks!

 

Glad it worked out, not my first B16/one piece header rodeo...
