Review on BBK 4009 - Chrome Finish Shorty Tuned Length Exhaust Headers for Dodge Ram Truck 5.7L Hemi: Boost Performance by Maurice Strawther

I'm already feeling better. A bolt from the BBK kit did not tighten properly and had to be purchased from a working auto parts store. Otherwise the product works great. Fuel economy improves by about 1-2 mpg. I have a 2005 Ram 1500 with 5.7 Hemi 4wd. Revain said it wouldn't work for my 4WD but said it would if I select 2WD from the drop down menu. I called BBK in Texas. BBK said the HD version of my truck has a different mount that doesn't fit. Non-HD models will fit regardless of 2 or 4WD. Since my truck is not HD, the product fits like BBK said. I am very satisfied with BBK 4009.
