    Hey all, I am going to be installing a ZZP down pipe and a new resonator, the bolts that connect the down pipe to the factory resonator are severely rusted and will need to be replaced. I am curious what size and length i need to get that will work properly. Any info would be greatly appreciated, thanks!

    youre putting in a new resonator and downpipe right just get some big bolts that fit in the holes and get them long enough that they go thru the flanges of your new items get some nice ones with corrosion protection if you can and make sure you tighten them down to spec according to the bolt maybe get a fine thread for more torque. you can do it all while the new parts are off the car

    I think they are m10-1.50.

    But most likely you will break them off when trying to remove them. I usually end up drilling them out and just using a pair of 3/8" bolts for the connection.

    Ya the reason I am installing a new resonator with the down pipe is because the flange from the down pipe to the resonator is all rusted together and everything, still have all factory hardware down there
