Got mine today and installed them.
My sound tube was also in the way.
These struts don't feel too "strong".
I have the MRTs on my '05 and they fit like a champ, and the hood would lift all way way after lifting it about 5" from the latch.
The Cal Pony ones I installed feel like I have to lift the hood most of the way.
Keep in mind this is my initial thoughts after only opening and closing the hood about 8-10 times.
I also have a pretty noticeable gap between the front half of the bracket and the underside of the hood. It is definitely by design and not install. The bracket fits around the curve of the hinge perfectly, but after the hinge there's a big gap.
How's everyone elses fitment?
These were installed on my '11.
