Today I used an Apple app to measure the noise inside de car. I know is not the most scientific study but is the noise level that I heard inside de car. The phone placed in the central cupholders next to hand brake
. Here are the details:

STI MY17 with KB ELH, HKS Funnel, Cobb downpipe, STP Exhaust.
Radio off, Aircon off
Tires 265 Bridgestone RE-01

Normal driving was btw 3k and 4k @50 mph. I did some pulls to 6k and when reducing gears was using heal and toe. Top speed during the pulls was 70 mph.

I lost the file, but remember that the highest noise level, using Z frecuency, was 93db. At ilde was 85db.

At the end I got a nice offer to buy the Q300 single Exhaust. One I installed will repeat the test
