Jardine is on, mostly
1st of all we had a good time, and that is what counts most. The 4" Jardine is on, all except the last piece of the tail pipe, and of course the SS tip which is back ordered.
Two hard parts; One was removing the stock system. Use a sawzall with a blade long enough to go all the way through. Got it off though via use of a manual (gasp) hacksaw. My less than a year old stock exhaust is sitting next to Jeff's horse corral. Two cuts, three pieces is all it took.
The other was the installation instructions along with some mods we found we needed.
IMHO Jardine needs a little better instructions

A diagram of how the pieces layout would be very helpful. It wasn't intuitively obvious to us backyard hacks exactly which direction the hangers should be installed, and of course we each had to try them in each direction before deciding that maybe we had it right. Their instructions for the piece that goes over the rear axle have a typo error, which caused us some head scratching. Also on at least the newer trucks, you need to remove the rear most hanger from the frame rail and do some field engineering with the sawzall. Without sawing this bracket in half, the pipe rubs on the forward most snubber mount. This was reported by ACoyle a couple of weeks ago also.
I will need to get the final piece mandrel bent to clear my mud flaps on my bed and get the SS tip installed to complete the job. I am thinking of having the entire system welded too.
My observations are about the same as others. A little deeper rumble on ignition, and definitely gets your attention when you get on it, but at cruise speed 55-60 and 1600-1800 RPM's it is essentially non detectable in the cab. With the windows down any extra exhaust noise is drowned out by the wind noise, at least until a healthy application of the GO pedal.
Overall it is much quieter than we were thinking it would be for a straight through 4" hole. I think I am going to be happy, I think it is subtle enough that my wife will still ride with me
Taking out breaks, I think it took us about twice as long as the 2 hours others have reported.
Great food Jeff, thanks for loaning the use of your shop.

PS: If anybody from Jardine is reading this, my comments are meant as constructive criticism, as I in no way want to slam you. That would be very ungrateful on my part, considering this was a prize and was 100% donated by Jardine. Thanks again Jerry.
