The largest benefit (as far as weight goes) will come form the loss of the cats, and if you have pup-cats. I'd say each main cat weight is around 20lbs.

I think mine came out somewhere close to 50lbs when I went to lg super pros with catless x pipe. That was on a 2002 coupe.

A 30lb weight drop is typical on 2001-2004 C5's when replacing the cast iron manifold's

AR Headers all the way; Ford, Chevrolet and Dodge chose ARH, along with most LSx shops across the country.
