Cool!! be sure to get the correct model number for the 6.0L engine. The Gibson model # is GP129S (the "S" represents stainless steel) they also have them in the ceramic coated style (GP129C) but thats a few more $$ or the more economic version in chrome # GP129 no letter after the model number). The 03-06 H2's get the GP500 model numbers.

Shop around the various sites to get the best price. Amazon, Summit racing, eBay, etc. Gibson Exhaust Systems - Mufflers, Headers, Tips, Metal Mulisha Exhaust Systems for Trucks, SUVs, Jeeps, Muscle Cars

When you order your headers, the box should arrive sealed. Gibson placed a seal on the top of mine assuring that all the components and parts were packed from the factory. Heres a tip; open the box and remove those gaskets, I noticed when it was time to install mine, there were several cuts in them from the weight of the headers in the box plus all the shifting around. Get them out and save them someplace or tape them to the outside of the box till your ready to install them. Plan on a full day of work or to have them installed at your local shop you trust. Don't forget to torque your bolts when finished and again after 100 miles or so.

 

Great! Thanks for the tips fyr145.
