Anyone know the length and diameter of the downpipe bolt's on the 3.8? Would like to stick with the stock size bolts and don't have a thread gauge/checker. Assume the 3.8 and 3.4 are the same but...

Will be replacing mine when doing the downpipe. Would love to know what size so, I can pick up some SS ones from menards beforehand. Sorry guys just trying to get everything together before the big job.

Id try asking zzp when you order the downpipe.
Will likely do this but, I am sure I have seen somewhere on here someone asking about them. I am sure someone knows

The length of the front is 30mm
The length of the back is 25mm

They're 10mm x 1.5 thread pitch

Don't forget to antisieze them to make life easier in the future
