Hey everyone, I drive a 2015 lexus is350 and I installed a remark axle back exhaust(muffler delete) which sounds really good already but when you get into high rpm’s there’s barely any sound. So i was thinking about doing ppe headers and then run a M-force pop tune. My question is would that be bad considering all i have is a muffler delete. i understand that i can’t find a video on it because everyone just runs a midpipe to go with it, but most people end up putting mufflers back on their car. thanks for the help!
