Yep... looks like the same system. Since I have only had them a couple of days, and I do not utilize any sophisticated mechanical measurement devices, I can only tell you how it feels to my ears, eyes and touch. Keep in mind that this is based on very limited usage. As for Horsepower and torque... I really don't feel any significant shift either way, but read Blackbeauty's response. I have only tested for Drone at the two speeds someone previously posted in comments, 35 and 55 MPH. So far... no drone up to 55. Haven't checked beyond that. As for the sound... I am no expert on the terminologies of automotive exhaust sounds... and it is such a personal thing to me. Personally I love it
. You may not. After a brief break in period I will upload some sound bytes.
for you reply.
