Son put a cold air intake on his Silverado. Don't know if it made any power but sure sounded nice, like an old four barrel carb. Gear change is a really good power improvement and with the high geared overdrive you don't really lose any highway driveability. I'd go to a 3:73 back there myself. I'm not a big fan of headers, too much heat and lots of aggravation. A good sounding muffler would be a good addition though. I'd like to have a report on the before/after deal with the tune, hear good and bad on that mod.
