Here are a couple pictures of his stock set up.
So I cut the DP about mid oil pan and slip on some 2-1/2" stainless tubing that was then bumped to 3" OD. Into a flex joint and then some more 3" tubing into a hi flow metal substrate cat (I probably should have moved the cat back a little so the hangers were on the tubing, but this won't hurt anything how it is now).
Installed
Some more 3" tubing and then into the 3" stainless resonator
The custom tubing that went around the gas tank and over the axle was done (me unaware of) in aluminized steel versus stainless. The bends around the gas tank were perfect but the bend up to go over the axle and some of the bends in the over axle tubing, still need some tweaking.
Then we finished off with a Magnaflow 14835 muffler.
This system is much much larger than stock and it's tight going over the rear sub frame and with original rubber hangers that are very soft I couldn't get the hangers to keep the system high enough so it sometimes hits on the sub frame. So the owner will either get new stock rubber hangers or some aftermarket hard rubber hangers. This system has 6 hangers on it and it moves much more than the Honda and Acura systems that I build with only 5 hangers. So I think Mazda must be using softer rubber.
