Sound clip of a muffler delete? This was mine. And I show under the car so you can see how mine was cut and welded straight through rather than "the pretzel"

 

+1 For straight through flow. The T on the pretzel can't be good.

 

The resonated XYZ pipe made for more of a restricted exhaust feel than the pretzel did.

With the stock exhaust + Pretzel, light flywheel, JWT pop charger and Osiris tune I got 32.5mpg on the highway.

I promise I'll get a video of it one of these days. For now here it is without the XYZ and with the stock heavy flywheel.

 

It sounds good, I heard it in person today!
