Well Im trying to put my exhaust back on the engine and putting it back on is the most frustrating thing ever![:@] I cant get the coupler to sit flush on the engine. When I try to slide on the header it just pushes the coupler out so it flares out to the sides when i try to slide it on. And when i try to put the coupler in the header first and try to slide it on the coupler just rolls up inside the header(I think thats what its doing because I dont see the end of it when the header is all the way on). Ive tried WD-40 and electrical silicone grease and nothing is working! If you could tell me what to use or show me a pic on what the coupler/ header should look like that would be great. I know we have discussed this before but it really didnt work the first time.
