90 ZR-1 Muffler End Tread Size
Ok, hopefully easy one, I just can't find the answer, or the right nut...
Getting ready to put a stock set of mufflers back on the Z, but the previous owner/shop welded the brackets to the Magnaflows. Got the kit on order for the correct brackets, but looking to determine the thread size of the stud welded onto the end of the muffler (See attached photo). Thank you in advance for the help.

Why the switch back to stock? To much drone.......I ask because thinking of adding Magnaflows.

Yes, Magnaflows are horrible. Previously owner apologized for putting them on.

Re: 90 ZR-1 Muffler End Tread Size
Ha ha! I know the feeling. Similarly, after years of Corsas and a few others, I tired of the constant loudness (not drone with the Corsas) so I switched my '95 back to its stock system. Gave me the stock look and sound I wanted, but as many here remember, I did have Marc add a pair of electric cutouts in front of the mufflers for when I wanted to go racing or just scare children and set off car alarms. Best of both worlds; I usually left them about one third open to provide just enough extra rumble when I wanted it. It was a perfect set up for me. --Bob
