Installed the HP2 on my 2017 Chevy Silverado 5.3. Very satisfied with the low rumble without being to loud causing a scene attracting police attention. Very noticeable without being overkill. Never been let down with flowmaster exhaust.

One thing to know before you get this muffler, in order for it to work properly, when installing on a stock car, you need to change out the resonator as well. My resonator was as big as my muffler, and no sound was getting to the muffler until I changed it.Your choice of resonator makes a big difference in performance as well. Great quality! Beefy sound

I had a Magnaflow 4in straight thru muffler installed on my Jeep Tj and it popped a lot and was way too loud so I installed this Flowmaster in line with it after and it still kept a low tone that sounds great and isn’t too loud and doesn’t do the popping sound

Stuck two of these in my Jeep behnd a stock 5.3L (300HP) engine. Purchased them as I needed something to fit in a small space. These fit the bill perfectly. They are compact and sound very good. At idle you can barley hear them, but once you mash the peddle you'll turn some heads. Hard to keep the foot at a respectible angle when you want to hear these babies sing.Almost 5K miles on them and I haven't noticed too much change in the sound. Hard to tell though as I wouldn't notice subtle changes since I hear them all the time.

I love the flowmaster sound. I hadn't tried anything other than there chambered mufflers before, but I needed something smaller and a little quieter than the super 10 I had on my Can Am Ryker. This is still pretty load, but it brings it down to a much more tolerable level now. And it sounds great, has a very nice rumble whe decelerating. The bike also likes this style of muffler a lot better as well. It knocked off .75 sec from my 0-60.

I put this on my truck today, it does not sound aggressive, or anything, just makes it even quieter, i do not recommend this if you want a aggressive sound
