Smile SOUND CLIP -- BEFORE AND AFTER RENNTECH SPORT MUFFLER INSTALL ON MY 2015 E63 S!!!

Here are before and after sound clips taken of my 2015 E63 S immediately before and immediately after the installation of Renntech Sport Mufflers at Mercedes Benz of Rockville Centre. Again to really appreciate the difference you need a subwoofer.

Before sound clip (stock mufflers):


After sound clip (Renntech Sport Mufflers):

Must sound better in person or at wot as I don't hear much difference in the clips... Both sound good... Renntech has a different pitch to it

Judging by your good taste in cars and mods I know they sound badass!! I take your word for it

These clips were taken by the dealership and they are very short. The Renntech sound is considerably louder and pitch is lot lower.

Thanks. You cannot tell a big difference between stock mufflers and Renntech sport mufflers playing it on a computer or iPhone because they cannot produce very low frequency sounds.

But if you can play it through a sound system with a subwoofer (such as a car or home stereo) you will see a massive difference in pitch. The Renntech is a lot lower in frequency. And it person you not only can hear it but you can feel it in your bones.

No disrespect but IMHO you get a much better sound by just removing the resonator...its a $100 job. I would rather get down pipes then the muffler, anytime.

To each his own. Great build btw, thumbs up.

Thanks on the build. I considered the downpipes but the power gain on Renntech's mufflers is greater than its downpipes and the cost was half.

Considered also removing the resonator but it is as loud now as I would want it. Love the low bass sound.
