downpipe question

[mikeymuscles82]

i just bought a megan racing cat back N1 style exhaust will this line up with my stock down pipe in my gst?

depends on what size your catback is..i doubt its the stock size piping. In this case you may want to invest in a megan dp that fits your catback or have a adapter flange welded on to compensate, but its restrictive.
