Thanks for any assistance

You can use the axle back rear section from any hatch though.

So here's what to get:
Mid pipe = dx/si hatch (cx mid pipe is longer I am pretty sure)
axle back = hatch are all the same size
cat = dx/si hatch, sedan, coupe. (del sol too I think)
header = dx/si hatch, sedan, coupe. (del sol too I think)

- Wed Oct 14, 2009 11:32 pm #150806 well i already got rid of the cx exhaust while i was doing up the car a bit last summer. it now has a dx header, si midpipe, teg custom cat (straightpipe with cat outsides) and now thanks ot a good days worth of work a semi custom oem muffler from a 4dr that i cut down and elded up to fin the hatch and i also cut the end peice off of it. and rewelded it at a different angle since well i was bored and wanted something different....

now lets just say its quiet as heck half the time im wondering if its still running.

and thanks for the help as well thats good to know stuff in case i need something else done soon with my b swap im planning
