    I have just completed my turbo project on my 93' hatch. It is a homemade(14b/turbo) and now I need exhaust. I still have the stock piping, any ideas on the size or brand. I was thinking Skunk2 but I was also thinking of jsut making my own. Should I go 2.5" or 3"? Also Should I get a test pipe or leave the catalytic in place?? Any experience here would be greatly appreciated.........thanks

    Definitely go 3" a 2.5" is too small for even the smallest turbo..

    I would go 3" deffinetly. I know for around 300-600 you can go from an HKS , Mushen, Skunk or Manga Flow system for ya car from the Cat back. Just some ideas to look into.

    see what i dont understand is everyone says "yah go with a 3" exhaust" but i just dont see the point when the turbo outlet is only 2.5 to have a extra 1/4" on either side of the pipe. can someone help me out there?

    Basically, you want to evacuate the exhaust gases with as little restriction as possible.
    3 inch will have less restriction even if the turbo's outlet is only 2.5

    Get a 2.5" catback. Mine is a Tsudo.Leave the cat in there. Then make a custom open 3" down pipe with a cut-out(manual or electronic) and 2.5" tubing back to the cat. Sounds confusing but just look at the set-up on this car HMT's Turbo Kia done...
