You can make more power with lower restriction exhaust, why does the factory not put the better flowing exhaust on the vehicle? The reason is similiar to the paper vs. cloth air filter.

I think your answer is in the read below. As far as the Exhaust goes... It has to do with a ton of other factors such as emissions,etc and other things that I'm sure F5 and our other resident HUMMER Engineers can explain when they drop by and read this post.

Your low restriction High Flow Filters Like K&N only flow so long before the oil in the gause starts to clog and slow down flow.

I use to use a K&N on my 86 Supercharged Corvette. After several months of driving it would start to clog up. I switched back to paper rather then go thru the hassel of cleaning it all the time. Besides...How much dirt does the K&N pass into your motor In it's Hi Flow mode..???

We could go back and forth here as some people like Chocolate and some Vanilla... So..as long as your happy with yoor K&N..that's all that counts.
