what size are these exhaust bolts!!!????

[salnazzaro]

Anyone have any idea what size the factory exhaust bolts are and the bolts for the downpipe too? I cant seem to find the right size. Thanks

I use a 13MM for the downpipe, the rest of the exhaust is 15mm if i remember correctly. The downpipe bolts must be taken out from the engine side, the other side is welded to the pipe. Also, a wobbley 13 comes in handy with a long extension for the upper downpipe bolt.

I'm in the middle of my install and just noticed down pipe bolts didn't come w my flo pro dp back dpf delete. What can I use?

You can re-use the stock bolts, if you can find new nuts for them. Or you could hit up the local hardware/home improvement store and find some that will work. The Flo pro stuff is usually in a little plastic baggie with the pipe, you get jipped? Sometimes the boxes get a little mangled in shipping and parts can fly out. Sorry to hear that.

My dad saved the day and had stainless nuts and bolts
