I have eBay headers, two magnaflow cats, both OEM resonators and a muffler.
Now that I have removed the UUC muffler, I put the stock one back and the difference in sound is huge. It's very quiet now but you can still hear then engine a bit.
I know that in the video it sounds raspy a bit, but in real life it's awesome. Loud growl.
