I installed my ZZP Catless DP this weekend (Great quality btw) and I previousily had the MD so I figured I would drive it around that way for a day since I already had a Magnaflow muffler in my room. Well Lets just say it was extremely loud and it would sound like a gun shot every time i shifted. I was also told that at night you could see flames shooting out of the exhaust when i shifted hard. Here is the MD and catless DP


Here is the Catless downpipe with a magnaflow muffler (sounds **** btw)

 

the ones you uploaded for the muffler delete is just a pic

 

thats exactly what mine sound like but louder

 

Fixed. Thanks for pointing that out man.

Yeah I am waiting for my muffler to break in some and then I am going to do some more videos of it. Its so quiet at idle but when I get on it, it opens right up.
