My engine is a completely stock KA24DE, This is a video of my new HKS exhaust that's coated in satin black. It has an 83mm tip and 75mm piping. Its tone is aggressive throughout the RPM range, but it isn't piercingly loud. In the video the first rev is to 3k the second is to 4k and the rest are between 5k and 6k RPM's. Under 3k it doesn't attract much attention at all and if you keep your foot light on the throttle you can get to a little bit above 4 without making too much noise. It's affordable, quiet, and low key most importantly. I love it.
awesome vid considering getting one for my s13
