HKS Hi-Power SPEC-L II installed today

I finished the break-in period so I took the day off to change the oil (1800km), install the exhaust, and take the car to the mountains.

My thoughts on the exhaust (hopefully helpful to others considering it): - I was in between the HKS spec L/L2 and the Borla S-type as I was looking for a better sound without being obscenely loud. I went with the HKS as the Borla was a bit more expensive for me. - Startup is pretty loud, but I guess that's unavoidable. - Idle is pretty silent with a nice low tone. It also pops a bit on downshifts. - Overall tone is low and bassy with no raspiness. I don't really agree with the reviews saying this has no drone as it's definitely there at ~3k rpm. I'm in Australia and cruising in 6th at highways I can hear drone, but it's very minimal. - You'll probably like this if you're after a "mature" exhaust that isn't too quiet.
