  10. Jevan HoffMan

    I would like to add 120 horsepower to my d15a3 but I want to keep it quiet I like to drive on the back roads of 109 of the coast and I started doing that in my 2001 d17 a2 Civic with the MagnaFlow exhaust and they changed the speed limit speed limit was 55 and you couldn't go 55 unless you had a car that could hug the road now they dropped it to 45 but I don't

    1. Jevan HoffMan

      Anybody to hear me going by how can I make my car quieter but I want it to flow can I do like a 2.5 in to the muffler 4 in out or something to quiet it down add more resonators but I still want more power when I added ECU and tune it

  11. Jim Hiscott

I apologize; I haven't been able to watch the channel regularly so I haven't been able to keep up with the Bug progress. Do you think you guys could collab with Wilkey to do some gnarly Bug stuff together?????? I LOVE ALL YOU GUYS! 🧡 Thank you for all that you do!
