Katzmans Caddy -> RE: need help on Escalade exhaust mod (3/7/2007 2:44:28 PM)

You know I drive a Deville and I also have a GMC (Yukon XL/Suburban). I love exhaust pipes and sound, that's why I have a muscle car in the garage. The Escalade/Yukon/Suburban exhaust sytem is a very good system from the factory. It varies from model to model but generally it is a dual system of 2.5 inches to the muffler and exits via a 3.25 inch tail pipe. I do not think the money spent will justify the small HP gains if any are realized. Most times these systems move your torque and HP up to a higher RPM range making any gains useless in normal driving, louder yes, but useless. I think that a Cadillac, even the King of the SUV Cadillacs, should be smooth and sound powerful yet reserved. GM already made it this way. You say you want to upgrade the exhaust but imo you'd be taking down to the gutter.
