I got my 02 GT with a set of JBA shorties already on the car. They cracked so I replaced them with a set of FRPP coated shorties. Had a guy install the first time with the frpp gaskets. With in a week they were leaking. Few months later I did the job myself. Dropped the K member, installed copper gaskets and locking bolts. Guess what, week later started leaking. I'm tired of these ****ing leaks. It's not like I can give em a quick tighten a week after the install since i'm dropping the k. Does anybody on here have any suggestions so I can get these damn things sealed? I heard good things about the percy aluminum gaskets. What do you guys think?
