About Borla Exhaust Systems
Borla Performance Industries (almost always shortened to “Borla”) have over 30 years experience building exhaust systems not just for street applications but also for some of the most competitive racing programs in the world. Led by Alex Borla, a man who can claim a number of patent holdings related to exhaust and muffler design, Borla systems are specifically designed to increase power and look good doing it.
Borla Performance
Borla states that its exhaust systems have been put together so as to offer a 7 to 10 percent performance gain over stock. All Borla systems make use of T-304 aircraft-grade stainless steel. Unlike some other exhaust companies, Borla does not go in for the enormous pipe diameters that are often seen on turbo or other tuner cars. Instead, the brand focuses its exhaust system development on maximizing exhaust gas velocity and improving gas flow from header to tailpipe. By avoiding oversized pipes, Borla is also able to maximize power without increasing low-end vibrations or droning, which helps to create a tuneful exhaust note that doesn’t set your teeth on edge.
Warranty Compatible
Borla makes the specific claim that the installation of any of its exhaust systems will not void the factory warranty of any automobile – provided, of course, that the stock catalytic converter remains in place. While it would be unusual for any car dealership to complain to a customer about an aftermarket exhaust system, for any gearhead who might have had a negative experience in the service bay in the past, Borla’s promise might carry some additional weight. Borla also offers a Million Mile Warranty for its products, as long as they remain installed on the original vehicle that is still in the possession of the original owner.
2011 BMW M3 4dr w/comp package and dct. Just installed borla dual exhaust and the drone is unbearable. I can feel vibes in the floor and in the seat backs at low rpms. Above 2000 rpms no problem. Any thoughts on how I can deal with this? thanks Ken
Ken – That’s too bad. Most of the people that install Borla don’t say much about drone (they’re quite a bit nicer than most after-market mufflers), but I must admit I don’t know too many M3 owners.
Have you tried calling Borla? They might be able to send you some venturies…otherwise, they should accept their system back on return.
Best of luck.
I am the one with the 2011 M3 4dr comp package and dct with the unbearable Borla drone. Borla first sent a venturi which helped slightly but still unbearable drone. They then replaced the exhaust system with the new ATAK exhaust. A little louder but no drone. Thanks Ken
I purchased borla cat backs for my 04 corvette and i love the sound,very happy with exhaust.i also have a 72 chevy cheyenne with gm crate zz4 with headers and custom stainless 3in exhaust with stainless flowmaster mufflers.Im 65 and is too loud especially at cruizing speed,a deadening drone.Would like to see,hear borla mufflers on similar application if available.
