Heard a strange sound from the motor driving this morning, and when i get home, low and behold, the top bolt from my collector to where the two pipes meet (its a DCSport 4-2-1 Header for the 2.4). If anyone has their instructions still, what size is that bolt (there's 3 total, they go where the two metal rings sit into the slots of the collector). I dont remember where my instructions are, otherwise I would have looked it up myself. If anyone knows please let me know, as now i have an exhaust leak, and plan on taking a roadtrip this weekend.

Go to your local gm dealer or parts store..get new studs..done and done..phil

Not on the header, on the flanges for the two pieces of the header, found my instructions atleast, the 3 bolts that hold the two halfs of the header together are M10x1.25x20.

gotta love people that can read ,

ida told ya , but i didnt see this in time to go measure mine

I read it and i understood it..hell if it was just colector bolts go to your local parts store find some that fit and thats it..not rocket science..
