    Alien Head 2

    Posted by LVD on Jan 30th 2018

    I received my Brock's Alien Head 2 full system last week. I decided to make it a one man job as far as fitting it goes, I had no niggles with getting the sytem on and it looks AWESOME now. I just need to fiddle with it to make sure everything sits the way I want but over all I am very happy with it indeed. Everyone that has seen it so far have commented that it looks great and everyone says it looks so much better than the average Joe's Akra/TwoBros/Leo systems. They all have also agreed that it sounds amazing, especially while quick shifting. My tuner commented and said that the pipe made him deaf while he was running her in his dyno room. He also said that she has made 4hp more than the highest S1k he has tuned, base run with my AH2 and DNA filter already netted 184rwhp and after tuning with the PCV we sat with a high of 189.6rwhp. Amazing sytem with an amazing growl from an amazing supplier. Thanks Brock's!

    I have had this exhaust for some time now, haven't take the time to write a review, no other reason that I am so stoked with my system I forget to thank you. The sound is purely amazing, horse power gain is noticeable to the point that don't need dyno numbers to tell me so and the installation is super easy with detailed instructions. I love the look and most importantly the performance!
