Flowmaster Cat-Back Exhaust Install on 2011 GMC Sierra
Installation of a Flowmaster Force II Cat-Back Exhaust (#817523) on a 2011 GMC Sierra.
I made this video because I was researching installing one of these on my
truck and I couldn't find anything for a GM Truck. I saw some Mustangs, some Camaros, some Ford trucks, etc.
But nobody had documented what it would be like for a GM truck. So here
you go. All in all, it was pretty easy and only took a couple hours. I
can't promise how close they are, but the instructions and kit were for
2007-2012 GM Trucks. So this would most likely apply to them as well, with
perhaps a few deviations.
Also, sorry for the fact that it's all close ups, but when your truck is on
ramps and your lying underneath it you can only zoom out so far.
[15 Oct 13] One more thing as a note on warranties. Here is a snippet
from the Flowmaster FAQ:
"There are some modifications that have the potential to void a vehicle's
factory warranty, but modifying the Exhaust system after the catalytic converter is
not one of them. All Flowmaster Exhaust systems are designed vehicle specific
and do not violate manufacturers factory warranty. If you're having
problems regarding this issue, please contact www.sema.org for more
information regarding consumer's rights on performance aftermarket parts."

car has a stroked 302 with 10.2:1 compression, a solid roller cam, and
aluminum heads. This car is a weekend driver, not a daily driver. I've been
