SLO247 1,713 Posted December 16, 2016 Anybody know what size the Welsh plugs are on the exhaust side of the crossflow? Share this post Link to post Share on other sites
ando76 4,354 Posted December 16, 2016 Go to precision internationals website. They have a great listing for x flow which includes x flow. I have 3 sets on my bench at work but I'm not 100% on the size. 2"1/4 comes to mind. Just check their website to be sure tho. Share this post Link to post Share on other sites
