2009-2014 Cadillac CTS-V Performance Mods Discussion, Borla Drone in Cadillac CTS-V Series Forum - 2009-2014; Anyone own a Borla cat-back system? I'm curious how the drone inside the car is. I looked on YouTube and ...
Not the same vehicle but I put a Borla on my Tahoe. That thing droned bad on the highway. Droned enough that I put dynamat all over the interior when I did the stereo. That fixed it but I would not do it again.
I have the Borla system on my car with the off-road pipes (no second set of cats) and the car doesn't drone at all. @ 70-80mph in 6th gear on the freeway it is surprisingly quiet. @ WOT it sounds awesome, I get compliments on it all the time. The only thing it does do that I don't like is it pops and crackles pretty loud in the morning between shifts, which may just be a manual trans deal.
I think it scares my neighbors
