Does anybody know what size bolts are on the down pipe, both ends? Im getting ready to change mine and know the will break or will have to be cut and I want replacements ready so I dont hve to wait to get my car back together.
Car is a 01 Grand Prix Gt 3.8 non supercharged. Thanks in advanced.
 


not sure on size, spray them down with PB blaster a few times and let it soak... mine came out with ease... just did headers and my exhaust manifold bolts came out easy with pb blaster also.
 
the manifold is NOT threaded. the heads are threaded. all of them are bolts or studs from the head.
 


Im going on what everybody tells me so fare. I havent actually got under the car yet other than to see the down pipe broke in two. Thanks again
