Weird exhaust problem
I can't keep my collector nuts and bolts on my car. The headers are Hedman shorties with the new style collectors. They are the ball and cup style that do not require a gasket. I used the nuts and bolts that came with the headers to bolt the Y pipe up and they fell off after a month of driving after the swap. I put some new ones on it thinking that I may have not tightend them enough and they came off again about a month later. The 3rd time I tried putting lock washers on them and after about a month, they came off again. The 4th time I used high heat lock tight and lock washers with new bolts and they came off again today. Since putting the locktight on, I haven't had a problem for 6 months. Every time I change my oil I put atleast 3 full turns tightening them back down. Has anyone ever heard of any problems with the new style collectors or know of a solution to this?
