Hello everyone,

I just installed an endlessrpm catback and jpipe. Surprisingly, it's really loud at 2-3k rpm. After 3k rpm, there's barely sound coming from the exhaust and more of my engine. For those who have aftermarket exhausts especially ones who installed the endlessrpm exhaust system, is this normal? I expected it to be louder than stock and the db goes to like 110. I double checked for any exhausts leaks and nada. What do you guys think?
