The biggest horsepower increase I've done for this truck to date as of 11/3/2013 was to add a new long tube tuned Exhaust header made by LCE. I noticed a dramatic increase in 'pep' from the 240k mile 26 year old 22R after I bolted this header on. Shed about 20lbs of Exhaust manifold cast iron weight in the process too!
