hey all,
I received my Flowmaster American Thunder kit for the H2 last week. It says that it works for H2's up to 2006.
Since mine was a 2007, I called Flowmaster and they told me that they haven't tried it on my model yet, and it "may" work.
So I took the exhaust kit to a muffler shop and
most of the kit worked except the resonator pipe. There was a size (diameter) difference where the stock pipes connected to the resonator. Plus he said there wasn't enough space. So he had to fab a new pipe where the resonator would of connected...
The exhaust sounds great! It's loud and makes the v8 sound like a
V8!
It's fun to pull up next to the ricers

They get scared when they hear a real engine!
The whole install cost around $150.00 at my local muffler shop. One place (a 'speed' shop) wanted to charge me $700.00 for the install... HAHAHAHHAHAHAHA I lauged all the way out of the parking lot....
Just my 2 cents!!!
