[QUOTE="swshawaii, post: 934682, member: 67547"] Consumed two full tanks using RichardL's "topping off" method. (Gas pump measurement, not fuel guage or low fuel warning indicator) Mixed city and highway average increased from 16.5 to 19.7 MPG. (40% City) Same route, driving style, and fuel. Engine mods are a Zabteck Throttle Body, K & N Drop In Filter, with the air silencer removed. Muffler is a Dynomax Super Turbo bought from Amazon for $45 shipped. (#17733) [u]CarReview [/u]says the [b]"best value in Motorsports and the most popular muffler in motorsports history is a proven winner". [/b] Anyone experienced similar gains by changing a muffler keeping the stock pipes? Consensus says it requires "break in" and will improve over time. Huh? Eddie '04 was right, the stock ST exhaust is a "cork". I'm pleasantly stunned. :banana: [/QUOTE]
