Justin: It's 3" mufflex ORY for hooker super comp long tubes
3" to a 4" collector, so I gotta pick up an adapter to go back to 3" for my magnaflow to work. The headers are getting an 02 bung welded in and coated at Jet Hot. I bought them new directly from jet hot, should get here in about another week.
