I have an 87 Camaro that I'm trying to sell but I need to replace some exhaust parts first. I can get the pipes pretty easily as I work at a parts store but the muffler I have to order. As far as I can tell the inlet size I need on the flowmaster I want is 2.25 but I dont know if the outlets need to be 2 or 2.25. If someone could let me know the stock outlet size it would be great.
Oh, the reason I'm selling this is so I have more money to put into my 83 HO trans am.
Thanks

 

doesnt that parts store computers tell you that like they do here it should be 2.5 outlet if its ho and 2.25 if its not
