Borla vs. Corsa





I did a LOT of searches through youtube and anywhere else I could find videos of Corvette exhaust.
I'll see what the file size is like when I finish it.
Can you attach a video in a PM?
Also love the look of the Tigershark tips!!

The Best of Corvette for Corvette Enthusiasts


Just was out yesterday for an afternoon and we have a lot of steep hills around and I purposely tried lugging the engine up the some of the hills and as subjective as it might be, Corsa's still have no drone(indy pace car ,x-pipe and headers now! However, have fun with whatever your decision is, that's the whole point anyway.

You will hear very drone prone exhaust systems at Carlisle, and these systems will all sound great at idle or when revved up... When we at GM worked with Corsa on the design for the Indy Pace car, I was specifically told by Corsa Engineers that they can bend the sound by tuning the exhaust chambers, but its always going to be a trade off.. there are three issues with exhaust harmonics.. idle, cruise and wot.. they can tune the sound of two of the tree to produce that optimal sound throughout the rpm range.. but you cant have great idle, great wide open throttle, and great cruise... you have to take from one to get the other...Development engineers at GM wanted no drone when cruising in the 60 to 80 mph (2500 3000 rpm range ) this was a very important feature.. and with the Corsa Indy pace car system being licenced by GM, they had to make it the way we wanted it. Thus the Indy Pace car system was born... The point being.. the system that have great Idle, have to give up great cruise... they all sound good at WOT, and its not the main focus of any designed system.. because its only for a relatively short time that you are in WOT mode. So what do you want , great Idle, or Drone at cruise.. you cant have both... if that were the case then we would have gone to that system. Drone was not an option on the Indy pace car system. So here is some insider information on the development of the Corsa Indy Pace car system. Does it sound as good as a drone prone system at Idle? No...
So at Carlisle you may hear some great idle tones, and WOT, but the real test is taking that system out on the road at 60/70 mph in 6th gear and listening to it for about 20 minutes to determine if you can handle that noise. Many members have PM's me over the years and fell victim to the idle tone.. most of the most obnoxious system sound great at idle.. So these folks bout that system only to have issues with cruise and in many cases, they had to sell them because of these cruise issues.. Ive heard many many headache stories.. many my wife wont get into the car since I bought the system stories...
So consider this, before you make a choice.
Good Luck

BTW this sound development is not a secret , any manufacturer of exhaust systems have their own engineers... they all know that you cant have it all... All exhaust manufacturers design their systems around these principles.. Borla wants a better sound at Idle, and are willing to make this system to appeal to those who only want a great Idle...They all sound good at WOT. They are betting that more people want better idle than want a drone free system at cruise.






that sound that the borlas produce is MY feeling of a pure quality sound.
which comes right back to the personal preference/subjectivity part of a 'which is best' type of question.
In the end, I like the sound of the Borla Stingers 100000000x more than the Corsa's (any type). That alone is enough to justify everything.
But even so, I don't see this "terrible" drone some complain about. Put another way, Borla Stingers is the first mod my wife wants to make to her vette. If the wife wants it, it can't be that bad.

OK IM done with this thread.. Ive offered some insider information, and some input I received over my ten plus years here... Good luck with your decision .

Almost sounds like it has a cam. As for the drone, do yourself a favor and take a cruise on the interstate with someone running Borlas.... no need for a test cruise with Corsas.... no drone...guaranteed.





Switched to z06 Ti mufflers with headers but found them too mild.
Finally ended up with corsa indy pace car setup and find them to be the perfect blend for being loud and quiet at exactly when i want them to be.

with my cammed 382 stroker. some friends have told me the car sounds down right evil especially at the drag strip. by changing out from the zo-6 ti's to extremes i also picked a mile per hour in et to 131.57 but the extremes also weigh 5lbs more than ti's.







I have the Corsa "Pace Car" system. Best money I ever spent.
