Is a performance catalytic convertor worth buying?
I'm upgrading my stock muffler to a flowmaster 44, and since the pipes rusted through all way. My catalytic convertor fell off, I'm wondering should I just get the OEM cat welded back on or spend some money for a "performance catalytic convertor" need help guys thanks in advance

I noticed a decent bit of improvement on my Xj.
But I had a custom 2.5" downpipe , hiflow cat , and catback welded up at the same time. I'm wondering what improvements my header will give when I install it on Thurs
