I first installed just the slip on and found it a bit too bassy. Then after installing the midpipe, the sound is just perfect. As with most exhaust the sound changes slightly after the pipes warm up. The Evo is louder when cold, even following cold start, and then gets quieter after exhaust warms up. I am always getting complements on how good my exhaust sounds.
