Well I just replaced my Borla stingers with TIs.I have a vert and I never put my top up and the stinger drone was killing me on short or long trips.It gets even worse when the top is up.I don't think it would help to put a sound barrier in the trunk or install sound proofing in the floor.I must say that I miss the muscle car sound of the stingers,Just couldn't take it.Then again I turned 72 on the 12th.

 

I have the B&B Bullets on my car and absolutely love them, however it is not a daily driver so i don't think its that loud. Some people have said they drone but they do not in my opinion. I wish they were louder to be honest.

 

I think the bottom line here is that you just have to somehow experience the sound of these systems for your self. Find some one to take you for a ride.

 

 

while i may have missed it in one or more of the posts above, flowmaster for sure (and i'm guessing perhaps other manufacturers also) suggest that you install a free flowing X pipe when you use their muffler systems....the reason.........??? it will greatly reduce (if not eliminate) the drone produced by the out of balance harmonics of dual exhausts. if you are old enough to remember, one of the most popular of exhaust options was "tuned" exhausts years ago. besides the sound, it was designed to harmonically balance the pipes, etc to eliminate drone of any kind. i have a rt 66 exhaust on my 04 convertible with a corsa X pipe and get absolutely no drone what so ever at any speed and for any length of driving time.

 

Loved my Corsa Sports that were on my C5

 

Drone is exhaust born cabin resonance, if it is enough of a concern for you go with Corsas. They are a good flowing system that sounds very good outside and do not effect interior sound levels...they are a bit expensive

 

In your search for an exhaust that best suits your needs, I’d encourage you to take a look at our newly redesigned exhaust systems.

For several years now we've had a deep, aggressive, muscle-car sound in our Corvette S-Type exhaust. You'll also hear this system called "Stinger" by our customers. That full-fledged note came with the trade-off of increased cabin resonance (drone). After much feedback from the Corvette community, we redesigned our exhaust systems.

Our new S-Type kit keeps all the character and traditionally aggressive sound while eliminating all drone at any RPM, in any gear. The same goes for our two other C5 options – Touring (mellow) and ATAK (our loudest). I've included a link to the original press release with more information below. Please reach out to me if you have any questions; my direct line is 805-246-6000. Best of luck in your exhaust search & happy motoring!

Oh, sure. NOW you bring these out. Where were you two months ago when I wanted Borlas but bought Corsas because of the lack of drone!!!
AAAAARRGGHH!!

Holy bologna , do these come with a set of long tube headers for that price?! And I thought the Corsa systems were ridiculously expensive...

 

That's what I was thinking, too, but Southern Car Parts has the Borla Sport system for about 1400 bucks. That's within $200 of the closest competitor, the Corsa Sports for the C5.

Good to Know! But I would also like to know the ACTUAL reason why all these systems, regarless of brand are so expensive.

 

Sorry, Corsas are the worst sounding exhaust you can buy, they look pretty, but have this god awefull fluttering sound at idle that just sounds like crap. They only sound good with headers X and a big cam! Sorry Corsa guys!!!

 

Apology excepted.

Love my GHL's, have a convertible and sounds great with top down or up. Look good too.

I just got mine put on and I drove around for a bit to see about this drone issue. First off they sound fantastic. I guess the main issue here is the fact that some exhausts are louder inside the cabin than someone would like...hence the phrase we want the noise outside the car not inside.

While the B&B Bullets are significantly louder than stock and louder than most aftermarket I did not notice a significant increase in cabin volume, it was louder sure, but that is because its a performance exhaust...I could hear my stock exhaust when I drove around too.

Maybe I just dont understand. It seems some people want to go aftermarket but not have the noise level inside the cabin increase...seems counterproductive to me. Thats like saying I want to put a supercharger on but I dont want any gains in HP.

Maybe I am...

 

Most aftermarket exhaust give tremendous, satisfying sound at WOT. But while cruising, whether at 30 or 70 mph, one would expect the sound of the exhaust not to vary much minute by minute.

Suppose the exhaust sounds pleasant while cruising at 60 mph, but at about 62, the exhaust sound in the cabin begins to get louder. At 65 it becomes so loud, one has to shout in order to be heard by the passenger. At 70, the sound reduces, and by 75 the sound returns to the level it was at 60.

That's drone. That's like your audio system sound like crap only between 65 and 70 mph, but normal either above or below that speed.

Members, please correct any errors in my description - I have Corsas, so I don't have drone, but I do remember having such an experience years ago with another vehicle setup.

amen brother to everything you said.
like wanting to put a lift kit and monster mudders on your 4X4 but not wanting tire noise on the road. i like the way my car sounds with stingers, and i'm the one who has to be happy with it.
they make all kinds of different exhaust systems and it's hard to give a good description to someone because what you like may not be what they like, and something may annoy them even if it doesn't you. i don't even notice any drone that i may have, and i don't personally care for the corsa sound. i may hear a car and say it sounds good, but i don't want that sound for my car.

 

As I have been reporting for years that Borla has drone at cruise speed... Even the Borla Representative agrees with this.. it has been there all along..And like all those Borla owners who are just in denial, after all they all made the decision to buy them and now have taught themselves to live with them... If you do not do any highway driving Borlas are fine..I feel that this announcement from Borla only goes to show that they have redesigned their system to match what Corsa has been doing for 13 years. At the time we were looking for an aggressive exhaust for the Indy pace car, one without any drone at cruise. Corsa taught us alot of things about exhaust shaping..
Everything is a trade off.. you can not have great Idle, great WOT and great cruise with no drone.. to eliminate the drone you have to limit the idle tone, ... conversely increase the idle tone, and you increase the cruise drone.. Corsa knew this 13 years ago.. So did Borla, this isn't secret stuff.. Borla bet on people wanting a great aggressive muscle car idle and were willing to allow drone at cruise to achieve this.. Corsa Bet on people wanting any drone.. and have advertised this with their lifetime guarantee. This is not a revelation.. I have been reporting this for over ten years here on this forum..
Driving around town with Borlas is fine because you are constantly changing speeds/rpm...So you don't notice it, But if you have a steady diet of 70 mph on a highway for an hour or so, you will pay for it.. I know many who get sever headaches from this drone after an hour, I also know of many people who bought them and now their wife refuses to get in the car.. which for some could be a plus... There is nothing more uncomfortable to hear than this drone while trying to carry on a conversation while driving down the highway for a few hours.
