I was on you tube today and came across a video that shows you how to make your stock exhuast sound deeper.Has anyone done this??

 

I dont know what video your talking about, but my brother drilled and cut out the end part of the baffle on the f4i I got from him. Its a little louder than stock and sounds decent at lower rpms, but still pretty quiet in upper rpms. I used to be all about loud exhausts but since every cop Ive ever had a run in with said I heard you coming, Ive decided to stay quiet. I wish they made aftermarket exhausts that are capable of more HP but as quiet or quieter than stock.
