The sound is perfect, loud and the perfect tone. I am finally able to hear the turbos, and you would be surprised how much more I can feel them with just a bolt on. There is no better option for an exhaust than the hpf set up."

8Ryan24707335i"Bought and installed the exhaust about 4 months ago. The build quality is excellent and the HPF team are very helpful when I had a question. Installation was very easy and seamless except for two minor things. First, getting the front section to mate with the downpipes was challenging, I ended up having to pry the two tubes apart about 1/4" to get it to fit with the downpipes. Second, I've messed with the location of the tips about a million times but they still hang down too low for my taste. The sound is awesome and very aggressive, lots of pops and burbles when you get off the gas. My only wish was that it was just a few db quieter, there are a few rpm ranges where the resonance rattles your brain. Tons of drone most everywhere too. When you buy this exhaust please realize that you're pretty much getting a straight pipe, it's going to be LOUD...good but loud."
