Re: Air sound out exhaust tips
Does your current set up have anyway for both cylinder banks to mix such as an "X" pipe or "H" pipe?
The suit case let both banks mix to help balance the sound.
Also at the slowest idle speed it can become a little rough.
Both Borla and Magna flow mufflers need exhaust gas velocity to cancel out certain frequencies. This is why at certain RPMs the exhaust is not that loud and accepetable, but let the RPMs drop and you get drone.
The drone is caused because the exhaust flow is not travelling at the velocity that the muffler was designed to cancel out unwanted soundwaves.
