That part number is not California smog legal and barely does anything for HP. If you want more flow, change the down pipe to something bigger and use the old cat. That would be a better way to get the missing acceleration you grave. :D

I did and the universal has an O2 bung in it that needs to be welded over. And yes it does make hp. Not sure on a NA car but on a FI I picked up about 17hp. I dynoed 120hp before and 137hp after my cat. I have the dyno sheet here somewhere.
