Default Bullets for Borlas

So I just purchased a set of Borla "S-Type" to go on my car because with my Z06 manifolds, these Bullets are just way too droney @ 70-80 cruise. Some tracks even have decibel limits that I'm likely surpassing, and to be honest, I haven't had much time out of the office to go to the track lately anyway.
As much as I hate to admit it, this car is really only seeing street duty now and I should adjust for such before I begin to lose enjoyment in driving this car.

My question is:
Does anyone know for a fact if I'm going to be any quieter than I am now, at least inside the car?

I bought some Dynamat Xtreme, Ensolite, and MLV as a backup, but would like to avoid adding the weight of MLV @ 1lbs/sqft.

If S type is the same as stingers then I don't think you'll be in for a very quiet ride.

My longtubes, offroad X and stingers drone like nobodies business at 70mph, even with sound insulation. I just cruise in 5th at 70mph and use 6th at 65 and above 75.

Crap.

I used Peel and Seal, which made a noticeable difference, but 70mph is still bad and likely always will be in 6th gear.

Interesting. The roofing product yeah?

Works OK as a CLD layer material, but I've heard of better results when used in conjunction with MLV decoupled by CCF.
Apparently.
I'll try it out and post back my results.

Yes, of course adding additional mass loading will improve any sound dampening :P

Don't anticipate stingers to ever not produce drone at 1600rpms though.
