    What Size Cutout for Firehawk?

    Hi guys, i've got a 2002 Firehawk that I put pacesetter longtube headers and a catted y-pipe on, but it still has the stock SLP catback that comes standard on Firehawks. I'm not sure if this is the same diameter as the regular stock exhaust that comes on LS1 f-bodies.

    Basically my question is what size exhaust cutout should I get if it's going on after the Y-Pipe on the firehawk slp catback? Thanks in advance

    The SLP "catback" on the Firehawk has a 2.75" pipe.
