Not sure if this is a good deal or if he'll sell the H pipe separately...

Kind of figured. Boss mufflers worth anything?

The picture on AM shows the side pipes and the H pipe ......so it is a different H pipe for the regular Gt?

I believe that it would not as the H pipe in that kit would be designed for a GT500. But, I believe that the side pipes are the same regardless of application. So you could buy the GT500 kit, throw the h pipe away, buy a Boss h pipe, and you would have the equivalent of the discontinued GT kit.

Or just buy the Boss parts piecemeal.

You will love it! Find a 5.5 mm socket to aid in install. You can use it to loosen the bolts on the clamps on the manifolds.

Very Nice. You will love them. Not louder, just better. Great find. These are getting rare.

This didn't work for me and I only had 4k miles on my never-even-seen rain car. Had to use a small crescent wrench on top and was finally able to get it loose. Such a pain. I ended up turning my clamps around when I installed the boss pipe. I absolutely love it though. Totally worth the pain it was to install.

Ok... Do not use the 5.5 mm socket to try and break the bolts loose. Once you crack them loose then use the 5.5 mm socket to speed up the process. Should have clarified. Congrats on the purchase!

I spent about 3 hours today installing these. Didn't have a 5.5 mm socket for use on the end of the treads of the bolt. Only had a 5mm and 6mm socket.
I ended up using the circle end of a 1/2" wrench and some WD-40 to turn it. Had to turn it a 1/16" of an inch, then place the wrench in the opposite way and turn it another 1/16" of an inch. Then turn it back towards me. This gave me enough room to place the wrench over again and turn it.


Then I moved to a small 1/2" socket and took the bolts off with that. 2 clicks per turn.
The tabs that held the clamp tightly against the pipe made it impossible to turn or rotate the clamp after it was loosened. Since I wasn't going to be re-using them, I busted them off with a screwdriver.

Then when I re-installed the new H pipe, I turned the clamps around 180 degrees.

It took a while but after that it was so easy! It sounds incredible with GT500 mufflers and no resonators!!

I'm starting to not enjoy the sound of this exhaust as much.

I think the Coyote is just an odd sounding engine...I miss the 4.6's note!

Wish you could hear mine. I was of the same though, until I heard my setup online. Trust me, do a mid muffler setup. You won't regret it.

Hey y'all! Not gonna read 14 pages of posts, but I ordered mine from White Bear Lake AutoNation about 3 months ago. Paid an arm and a leg. Install went smooth, no real issues with those tine inverted bolts up front. Running no restrictor plates with GT500 axle backs. Love it to death. Wouldn't change a thing.

One of the great things, to me at least, is that it has a low growl at idle or even 1/4 throttle, but WOT is just awesome. Especially to the guy next to you on a straightaway, LOL!

The fit is not flush like on a coupe. The sidepipes hang down further. Serious consideration if you are lowered. Also, the side pipes rattle occasionally on the sub frame braces. Other than that, it's all good.

Haven't had any rattles here. I love the pipes, give a surround sound affect. It is nice to have the electric cutouts to adjust the location on the fly. Typically leave the about 1/2 to 3/4 open most of the time. Pair up really nice with Roush Axle-backs and the GT Trackey tune.

You have a hardtop so the pipes will fit better. I thought about the cutouts, but just run with no restrictors, not too loud IMHO.

gMan--any chance of getting you to post pics of yours, showing the ground clearance. I have virtually the same 'vert/suspension setup as you. I've been reluctant to pull the trigger on the Boss setup because of the lower mounting. TIA
