@@dangle520 with the oem cat the hks exhaust drones quite a bit on the highway. With the test pipe and hks exhaust, there's almost no drone on the highway. Having a testpipe reduces the drone a lot
@@dangle520 the HKS single is a lot louder than the 60mm HKS dual. I cruise on the highway around 3-4k rpms and I have no complaints. To be honest, the only exhausts that are completely drone free are OEM or Tanabe. Or keep your HKS single and try out a Berk HFC. Honda's in general always have drone issues. I had the same problem with my 9th gen si
@@espadamedia I think I've read that the HFC has more drone than the test pipe, recently got a hardtop so the in cabin droning is a lot more than it was with the top down, so I'm just trying to make my car quieter. The HKS single doesn't drone above 70mph with a test pipe.
@@dangle520 ya you're right, that's why i went with a TP for my exhaust. Cats on this car seem to hold a lot of the drone. I guess the hardtop seals in a lot of the noise too. Not sure what else you could do to combat drone other than getting a different exhaust. You could even try using a silencer
How's the drone on it?

@@espadamedia what about 3-4k rpms? I have a HKS single with a test pipe and drones at that rpm level.
