now than on to the INSTALLATION

the most challenging part of the installation are the oxygen sensors because you have to weld in their bungs, I say this assuming most of us don't own a welding machine, I recently bought one and will be welding in mine, but you have a choice to take your vehicle to a muffler shop and have them weld in the bungs or you could buy these special strap bungs that don't require welding and all you do is drill a hole and just clamp them around the exhaust pipe

I strongly recommend welding your bungs in, as the slightes leak will skew the O2 read outs

a step drill prooves very useful when it comes to making a 1" hole - Harbor Freight $20 bucks
