Re: 97 Z71 driver/project build
well, I have put about 3400 miles on it and so far so good. since putting the stock size tires on it and exhaust upgrade, I have been averaging 17.4-17.8mpg, 75 miles round trip daily, mostly highway and interstate. About my exhaust upgrade, I put 2, 2" in/out flowtech 18" glasspacks on it with turndowns, it sounds ok but not quite what I'm looking for, It is tight under there with the dual pipes, I did some measuring but I think for a flowmaster sized/turbo style muffler to work I would have to get center in/out and those mufflers are kinda pricey, anyone use the dual in/out mufflers from flowmaster or thrush on this body style? any suggestions?
