I bought a set of Z1 HFC used of someone, the fitment was great the sound is amazing and i have it paired with a muffler delete. Its loud but it screams at wot there is a slight hiss from time to time. I didnt use the z1 gaskets because I was told they are trash. Highway drone isnt that bad. The guy who help me install it had testpipes with muffler delete and I didnt like the rasp this is definitely the way to go if you want testpipes deep sound without rasp and smell.
