Nah, just run a pipe to the cats directly from the smog pump. I would not run cats on a 95-down car because of all the ridiculous bull**** that attaches to them. Trashed this crap, plugged the heads after removing the crossover, G2G. Swapped in the stock pipe every 2 years for emissions.
2000 Mustang GT Steeda #0048 34k miles. 99 Cobra 4V swapped, FTBR IRS swapped, exhaust, tuned by James Gordon.
Just because I give you advice, doesn't mean I know more than you. Its just means I've done more stupid ****.
