I just got my DC header today and installed it on my XB and know I have a huge exhaust leak and dont know what to do. I followed the instructions and tightened the bolts from center out and the spring bolts are as tight as I can get them. I think it is coming from the spring bolt area anyone have any suggestions???

 

replace the exhaust "donut" gasket.
sounds like it is missing or damaged, happens easily.

 

Ok I went back out and took it apart this morning and realized I am a jackass and forgot the donut gasket. I'm an idiot.
