Hi, I'm in the process of putting a T25 on a 90 CRX Si and I thought I could use the dsm o2 housing, but it's too close to the crossmember. How could I make a downpipe or could I just take my car to a Merlins or Midas and have them make me a DP. I don't care what it looks like, just as long as it's cheap and it'll last for a while. Any help is appreciated, thanks.

 

what piping should i use for the downpipe though? Also, can a shop weld to that cast iron the the stock o2 housing is made of.
