ok so 3 weeks ago me and my friend installed my vibrant header and DP now the 3 bolts that connect to header to the DP we could not get the top bolt tight at all getting a wrench on it was next to impossible we did it the beswt we could and put some locktight on it there was always a small exhaust leak from there but it wasnt bad enough to bother me but i was just checking out all the bolts again today and the top bolt has backed it self completly out i jacked it up but i cant get a wrench on it to tighten it i did it by hand but thats not gonna be enough, can anyone help me out on this, i know a few ppl on here have that set up what did you guys do to get it tight
im thinking of bringing it to an exhaust shop to get it fixed

 

Shallow socket, swivel joint, 1 foot extension. To hold the side more towards the header, a simple wrench. Who ever holds the wrench needs to hold the socket straight.

 

hmm guess im makeing a run to the store
thanks artic

 

That work for ya?

 

i tightened mine from the top of the car with the hood open. you can get in there, it's just tight.

 

put car on jackstands, use a 3/8 drive ratchet, and a 15mm deep socket... all good. I never had any problems doing it this way, and I've installed at least 15 cobalt exhausts. headers and dp's
