This thing is amazing. I’m new into the car modding scene and was looking for a deep sounding growl. So I went and looked online for many catback systems, but this one stood out to me the most as far as the sound I was looking for. It was shipped to me I think within two days, not quite sure the exact time frame, but it was fast. The box was torn a little, but everything on the inside was in mint condition. Took me less than two hours to put on. Would have been less, but like the new car modder that I am. I didn’t have everything I needed right besides me lol. When I was done, I got my friends around to do its first cold start. It was absolutely a dream come true. The deep tone and sound had me so happy that my first purchase wasn’t a downer. When the cold start was done, it was a nice light deep tone. Not too annoying at all during idle, but that cold start is gonna wake the neighbors lol. When this thing hits those RPM’s. The sounds comes back and fills the air with that deep, “I want you to notice me sound”. And if you rev match good, it gives wonderful pops as well. Thank you guys so much for giving me the best experience a newbie like me could ask for. I’ll eventually make a YouTube video on the sound of it. Thanks again.
