have you had this problem with that i am about to explain. this is using stock manifolds to an aftermarket x-pipe (upr). the pipe is tightened all the way it can be onto the exhaust manifolds but there are some factory metal spacers (that are on the stud) there and i cant tighten em down any further. so im about ready to say f**k it and buy some aftermarket shorty headers so i dont have to deal with studs.
