Just recieved my 4" exhaust and found out that it doesn't have a bung welded in the downpipe for a pyro. I havn't ordered a pyro yet but want to install the exhaust this weekend and would like to weld in the bung while I have it on the floor. What thread size bung do I have to get? Thanks
i dont know, but most will recommend putting it in the exhaust manifold, before the turbo. that is more accurate. you got the EGT gauge to monitor the engine, not the turbo temps.
