I just installed the new Helix Test Pipes **Vids Inside**
My HF cats were rattling non stop for the past three weeks so I decided to swap them out for the new Helix non resonated test pipes. According to the butt dyno my car pulls noticably harder from 3000 to redline . The car is noticably louder from the outside (the new testpipes did not transfer more noise to the cabin ). I like the new exhaust tone (since that is subjective I'll let you decide for youeself ).
