Trying to gather some info on the stock exhaust bolt sizes or aftermarket sizes if they are similar.

the spring bolts for the downpipe are obviously oem and can be found easily

More interested in the Downpipe to CAT bolts

And Cat to midpipe bolts/nuts

Have searched to come up with nothing. someone said the down pipe/cat bolts were 1/2 inch. can anyone confirm this or offer any more info.

Will update this thread if it helps someone.
