Question David...
We redesigned our S-Type for the C6 and tuned out the drone. It's called the "S-Type II". Give me a call at 805.246.6067 or send me an email to davidb@borla.com and I will find a solution.
In a couple week my ARH catless pipes replace what was left of the stock stuff...and yes...I have my fingers crossed I didn't bring back the possibility of drone.
So...if I didn't have it before and now add headers...what do you think? Yeh I'm going to pick up 50-ish whp with a retune and pulley adjustment and my wrench says you won't have drone if you didn't have it before....but it WILL be louder....
I'm ok with that because obviously I can control the LOUD...
What is your prediction David? My opinion is your description of the S-Type II was spot on. I was like a ping pong ball going back and forth making the Borla decision vs.....but that's another story.

Reducing road noise will reduce drone somewhat but a bad case of drone will overwhelm just about any reasonable sound deadener installation. Just my opinion, but I believe that drone is best resolved within the design of the exhaust system not through the application of 100 pounds of sound suppressing materials. For me, in the future, about 30 pounds of deadener is the limit that I would be adding to any car. If more is needed I'll be looking at other options.

i agree, it is overwhelming, i think sound deadener might not do it, but would be good for road noise and such, which it is designed for. the exhaust has to be altered somehow, am leaning towards the Solo J pipe. people that have it, say it is the answer, but same token, people that add sound deadener, say that is the answer.

I have a '13 A6 with a set of Pfadt LT headers and midpipe and a set of B&B PRT mufflers. The car is quite loud, when I want it to be.
Prior to installing the mufflers, I put down 2 layers of material throughout the entire vehicle when I installed my sound system:
layer 1: Damplifier Pro

this will kill any vibration that the panels of the car experience due to the road as well as the exhaust.
layer 2: Luxury Liner Pro

this will absorb any noise coming into the car that isn't caused by the body panels vibrating. It will also kill your tire noise, etc.

I used the "Thermal Block" on the tunnel and it worked really well for heat reduction, how many sheets of each did you use or did you get the Corvette Package?
