Excellent Low End and Awesome Sound
I wanted to wait and drive a bit before I reviewed the Kooks Long Tube Headers. I installed the Kooks LTH's and H-Pipe on my 2010 GT in September, and it was totally worth it. My low end gains are very noticeable and the sound is awesome especially through the Flowmaster Outlaws. My first test was on the dyno. When your mustang is in the middle of a pull and everyone is plugging their ears... well, what can I say other than success! My second test was the Arkansas Dragon and Pig Trail. One word... Awesome! However, I see a brake upgrade in the future. Like Others that have installed LTH's, doing them on jack stands is doable, but a major pain. The other thing that I don't recommend is doing them by yourself. I had well over the typical indicated time (8 hours) before I enlisted the help of a friend. I absolutely recommend the Kooks Long Tube Headers and H-Pipe.

Superb combo!
This is a conveniently priced/paired combo! Long tubes really deepen the exhaust note!
