I have used Magnaflow mufflers on over 10 different vehicles for many years. This was on a Volvo C30 5cyl Turbo. Very soft upgrade. Noticeable in storage, but not noticeable. I also removed the center tube resonator. I hope it gets a little louder if I replace it with a downpipe without coils. After a few days of driving after installation, it became louder by about 3-5%. I don't really like super loud straight cars... but this app could definitely be a bit louder and more aggressive. Some OEM sports cars have louder exhaust systems.
