Excellent gains! The Dundon team and products are top notch. In terms of lap times, you should consider your brakes as an area of opportunity as well. We've had several customers drop a second or more from their lap times. It's not uncommon at all. You'll gain a host of convenience and cost benefits as well.

Great post OP, thanks for all that data. Why did you decide to keep the stock center muffler? Was it to keep the sound down a bit or was it for cost?.
To be honest, I wanted to stay below a certain number for the entire package. It was important that I got the throttle body, and plenum vs spending the same amount on the muffler that I don’t “need” to get the majority out of the system. NOW I must say the loud muffler is absolutely the play if you want it to be loud. It’s very sociable with the stock center muffler. The other bonus is that if I wanted to upgrade to the loud, I don’t need a new system just a minor modification to one pipe.
Cool guys at Dundon. Came up with a good solution for my budget at the time.
Cool, that is what I was thinking as well. I hesitate a little on the complexity of the plenum/tb install but it seems like it is the way to go especially on the touring
I felt the same way. It was not until a friend of mine had it done, that I realized how simple it actually was. (not for me) but for a tech. Dundon provides really detailed instructions with all the tips and tricks. I have spoken with a few Touring owners who said the entire system really woke the car up on the touring even more so than the PDK winged GT3 like mine.
I loved it so much that i had the kit installed on my 'new to me' RS before I even got the car!
I received my Dragy last week, and was able to do some pre-install tests over the weekend. RS will be dropped off for installation this Thursday.
Two 60-130 runs. Taken back to back, in opposite directions, along the same stretch (In Mexico, of course). I'm very excited about the upcoming installation, and will go back to the the same place for post-install tests.
Hey, I just realized, Dragy is picking up incorrect temp and altitude data. Actual temp was 55F, and actual altitude was in the neighborhood of 650'.
I can only assume Dragy is picking up incorrect density altitude also. There is no way it was -350'. (I'm a pilot, so I know how to figure density altitude. I didn't do so, but I know there is no way it was -350'.)
And up next "Hey guys, Phil here from Fabspeed....."
