Exhaust Fitment Questions

Hello EvoM, if this is in the wrong place i am sorry, but i have a few questions.

So i have the MAP o2 Dump housing (not installed), along with a aspec titanium test pipe(not installed) and a tomei titanium cat back (on the car). The one piece i am missing is a down pipe. So i bought an ams down-pipe, just to figure out you need the full ams exhaust to run it, so i sold that and bought another used down-pipe. The seller didn't know the brand but he stated it was for stock turbo fitment, when i got the down-pipe it doesn't mate up to the o2 dump housing, the dump tube hits the down pipe and the flanges don't mate up. Im sick of getting these downpipes that don't fit so i was looking at the DCSport down-pipe that takes away the test pipe and bolts right up to the cat back, can anyone confirm this will work with the MAP o2 dump along with my tomei expreme ti cat back? Any reviews on the DC Sport down-pipe? (fitment, install, quality, sound) Thanks everyone.

that's not going to make a difference if the o2 housing is what's causing issues

call MAP and talk to them on the phone. they'll be able to tell you what will fit and what wont

You need to run a stock frame downpipe. The AMS would have worked if you changed the flange as its 3bolt rather than 2bolt. The ams downpipe is the same length it's the parts after that that ams uses different lengths.

As as far as the D.C. Sports one I don't see a flange in the back so I guess one would need to be welded on. You could also contact map if your unsure or buy a DP from them.

I had a dc downpipe with the cat delete and it mated fine with my megan 02 housing. I now have a megan downpipe that mates up to the megan 02 housing. Only swapped it out bc NJ requires a catalytic converter for inspection. Not sure what downpipe you have now but most should mate up to the stock frame 02 housing (dump) unless something is off with your dump tube.
