View Full Version : 67 camaro ls1
I am going to order my exhaust and want opinions on sound and performance on 2.5 or 3 inch exhaust. What would be better on a stock ls1 with mac headers in a 67 camaro. I am looking at flowmaster 40s
thanks

I have a 3" on my 67 with a LS1. We put in a X pipe and 40 series Flow Masters. It is quiet at a idal but sounds good at rpm.
