  • most power gains from exhaust

    what are you guys running, and does any one have any dyno #'s to show what they gained with catback exhaust systems for an LT-1 car with a single cat?

    There really isn't much to be gained on a fairly stock LT1. On my 96 WS6, I ran 13.18@104.9 on a 1.87 short time with stock exhaust. I then put a SLP 2OTL cat back on and ran a 13.11@104.9 on a 1.88 short time.

    Not worth the money until you start making more power.

    As an aside, I ran 12.15@111 with the stock exhaust on the TTA. So the 2.75" exhaust will flow some air.

    Just something to think of...
