downpipe with magnaflow/stock main cat?
Does anyone know of a downpipe or pre-cat delete that is compatible with the stock OEM main cat or the Magnaflow replacement?

all of the JDM ones will, they didn't have a separate pre-cat/connecting pipe thing like we had.
the RB 2.5" one can be made to fit, it needs to be cut and have a 2" or so piece of pipe welded in. or you could buy a pair of flanges, and make a short pipe.

A 3" flange will bolt to a stock 2.5" flange if you use an intermediate-sized metal-ringed gasket.
I used a Vibrant 1465 (2.75") to bolt a 3" midpipe to the stock y-pipe, with good sealing. You could similarly use the gasket to bolt a 3" downpipe to the stock main cat.
Another part like this (3" diameter, but stock fitment) is the Corksport downpipe, though it is out of production.
