Magnaflow high flow performance catalytic converter. My daughter said that white stuff on the console lid cleaned right off. I told her it looked like bird poop, lol.
Great ride. I have a 1995 Firebird Formula and recently got it. So far it needs a little work like new headlight motors, exhaust system, and a paint job, but drives really great outside of those issues.
I know that's not the factory cat converters but that's all I know. You may need 02 sims since you have long tube headers. I do know they made less than 1500 firehawks each year for the LS1 engine.
