I have a 99GT with 165,000 miles on it. Decided to change the clutch this morning and of course I ran into a problem. The exhaust manifold bolts that hold the midpipe on are a lil rusty. I sprayed them with PB and am patiently waiting, already tried impact and a foot breaker bar, bout to go find a biger bar. Anyone else run into this problem. My 300zx was the same way so I left the exhaust up and did the job around it, hoping I dont have to do it like that again. Thanks Kevin
