i am runninf invidia catless front pipe and tomei unequal headers and bought this over a buddy club. i kid you not this thing sounds sexy and loud as hell. if you like aggressive note go for it

I spent a lot of time looking and listening to many combinations of exhaust. The Greedy was by far the most aggressive rumble I could find. The installation was quick and I am still in love with the sound and feel! 5 out of 5 on sound and looks!

Since purchasing my car and planning aftermarket upgrades I knew that eventually I would want an aggressive, single-exit exhaust.   After upgrades that were more about gains than aesthetic I started listening to clips online and discovered that a lot of single-exit catbacks sounded great when everything else was stock, or maybe one piece changed, but full exhaust cars with single-exit cans generally developed a nasty, metallic rasp and tearing sound.  

I pretty much gave up on the single-can option but, as I was deciding between an Invidia or Dezod setup I heard a clip with the Revolution RS and full exhaust that finally sounded right to my ears.  I wanted a sound that would do well in a "Pepsi Challenge" with a WRX and that's exactly what I got, paired with the JDL catless UEL header and JDL "Ultra Quiet" Over-Frontpipe.    It's quite loud, to be sure, especially cold starts.  But I love it.

Exhaust sounds amazing, it is a real head turner. Everyone wants to look at the car that is making that deep low tone exhaust note. Its phenomenal, all the videos don't do it justice. The biggest issue everyone seems to be having with this is how does it connect with stock front pipe. here is solution. If you use stock gasket and stock bolts, it is a little hard to instal. you will need to compress the springs on stock bolts, to connect it with front pipe if you do the compression of bolt springs it connects like a dream. Rest of the exhaust alines perfectly with everything it needs to aline.
