I just got the Cherry Bomb Extreme muffler put on today, man this thing is badass!!! It's 3"SI/2.5"DO and I kept the 2.25" outlet pipes from my previous muffler.

Here's a sound clip I took of it when my buddy ran it around the block, the camera work ain't the best but you can definately still hear it.

I'm sure your neighbors love you now too...

 

I am sure they will get over it. lol. That would be too loud while driving down the road for me, but it still sounds really cool.

 

It's actually not too bad while driving

 

Here's another clip driving around

The only thing I heard from that clip was the open window.
