i use to have the skunk2 on my accord...its not really that loud...
i also got the greddy evo2 ..its louder then the skunk2 on the highway..it sound nice and alll.i travel on 495north alot in the weekend and its not bad..i perfer going with the evo2 full catback then the skunk2 axle.i like how loud the evo2 is on the highway..but i have to turn up my music a little higher then with the skunk2 on the highway..with the skunk2 i can still listen to music at a low volume..
if it just a axle exhaust it doesnt sound loud at all ..unles its a full catback or a axle exhaust with a custom 2.5 pipe all the way...the hks hi-power is loud..but its not if its just on a stock pipe..not loud like it should be..just nice and perfect..
btw i would never drive on the highway with my kids in my car after i got the evo2 on it..
