Ok one of the bolt or studs backed out and fell out on the passenger side of the motor. Towards the rear. I need to get a new bolt or stud. But I am not sure which it is, or what size it is.

So what is it a bolt or a stud. It was the last one on the passenger side. Thanks Jason

 

Ok I think I found the bolt size. Is this right 8mm X 25mm For the stock bolt size and stock header. Looking at the JBA header Instruction, or do they use longer bolt.

ttt I really need to know the stock size ehaust bolt/stud Not sure what it really even is.

 

i have removed mine about 3 months ago,i've put long tubes on.

the stud you are asking about takes a 6mm wrench to remove them in 03 models.

hope this helps

 

mine's not a lightning (I wish), but I think the exhaust studs are the same. Mine are studs & nuts. I bought a new stud & nut from my dealer from about $2.00 - they stock them, so you shouldn't have a problem finding them...If you do, I may have it in the garage - I put headers on instead of a new stud
