Tx Marlin,
so far all in, all good but was night mare. as above
I would improve the model by just using a metal saw and ADD at the outer end a "cut", so I can use screw driver to get the studds out....on exhaused side (intake is I judge good per your exp., TOP)
TX to the easy but BIG VALUE insight
(securing look nuts: the car came with intersting I have never seen "looks" per washer with small theeth, they go OVER the very speacil bolds (with a trenche/gap) and lock against the tubes ..cool suff )
Danke
Mat
