I welded mine too, but not until i drove it 3-400 miles, and made sure nothing rattled. It's very tight quarters over the rear axle. Mine was okay, but many people needed to make a couple of minor adjustments, before they got it rattle free.

Avoid the H-Pipe from the GT.
Get the whole sheebang at once.
But be aware, You will loose low
end torque going from a single
2.5" to dual 2.5" pipes.
Putting an OEM GT exhaust together
from pieces can get as expensive as
a complete system DESIGNED for the V6.

Or get the FRPP V6 set-up.

What is the reason for staying away from a GT takeoff H-pipe? I have that and GT takeoff mids. It's good stainless steel and I'm very happy with my setup.

Why is low end torque lost? Is it still lost with my CAI? Just curious..? If so how much/noticeable is the loss?

I have a set of stock OEM hangers, 2 of them, I'll sell the set of two for $49 shipped to you.

Hmmmm.... well, I have not yet installed the duals completely... I have an X-pipe (pypes) and mids (newtakeoff GT) awaiting the process... but do have a NTO GT muffler on the car.

Didn't notice much in the way of torque loss.... and really.... unless you like roasting the tires off the car... we're not in the <2k RPM range for long....

Perhaps I'll notice it more once the duals are in. Meanwhile, flashed for 93 octane with my X-cal.... THAT was a very noticable improvement all around.

@157db: EXCELLENT link. THANKS.... I've been wondering WTF the P/N is for those "Exhaust Couplers" was for some time now. From the looks of it, to splice in my "stuff", I'll need one of those... and the rear hangers of course.

I find it dubious that you can get the S.S. version from the aftermarket considerably cheaper than OEM from FoMoCo too...

The S197 4.0 V6 and 4.6 V8 both use 2-1/2" mid/over axle pipes. This is the reasons you can just swap a stock V6 muffler for a stock GT muffler is because the pipe is the same size.

The factory hanger bolts are thread forming so the easiest thing to do here is remove the bolts from the passenger side and use them to form the threads on the drivers side, the holes are already there they are just not threaded. To do this just hold good pressure against your ratchet as you screw the bolt in. Then just pick up some standard bolts the same size and pitch at the local hardware store to replace the ones you remove from the passenger side.
