mine was loud at the beginning, it gets quieter over time as it gets worn in. It still has noise at the 3k RPM when WOT

I have had my kit for maybe a thousand miles. I find that it's all about the amount of throttle I give it for the noise. At highway speeds 65-70mph with cruise on its rather quite. I still might add a muffler at the end to quite it down more though.

Today I had a buddy drive my car around so I could hear the exhaust from the outside. I have to admit that this exhaust sounds pure BAD ASS! It really sounds good from outside.

I just wish it wasn't so loud on the inside.

After my warranty is gone im just gonna do the downpipe and mbrp all at once. I hope its got the same kind of drone to it that my muffler delete has and the loudness. All the clips sound great so far :)

Keep in mind that the MBRP exhaust flange is not 3". It's only about 1/4" larger than the stock downpipe outlet flange.

It's not the end of the world but it's worth considering if you want ultimate power out of your downpipe mod.

I welded in a small Magnaflow race muffler. It was the largest muffler I could squeeze in without having to rework the bends. Its still loud, but it took some of the edge off.

I don't have a device to properly record sound or video. It sounds the same actually, just a little less loud. Tone or sound didn't really change. Unfortunately the annoying drone is still there, just not as head pounding.

I was thinking about adding something similar to mine. How much did the muffler run you if you don't mind?

That drone is pretty killer in that 3-4k range. Ive found that if I keep the shifts light its not so bad and cruising speeds so far are tolerable

Regular price was $150, but I got it on sale on black Friday for about $112. It was definitely a pricey little thing, but I guess its more heavy duty than their regular street mufflers since its a part of their "race" lineup.

I also considered the Dynomax mini race bullet muffler, but I wasn't sure it would have made enough difference since it has less sound dampening area.
