lol, JKing...no benefit other than looks, but if you want the burnt tip look check out the GReddy or Megan exhaust that is made for our cars so you don't have someone hacking apart your stock exhaust

 

I was searching for the Megan exhaust and saw these. I didn't understand why someone wouldn't pay $100 more and get the system.

 

These are targetted for more of the 4cyl croud...just cut the stock muffler off your Honda or whatever and weld this on. Our vehicles with dual mufflers add to the cost of the exhaust system, but it is also a Lexus which would lead people to believe you value quality, so you have to pay to play sometimes...there are a number of great value exhausts out there, the M2 is a great example

 

I love your choice of words here lol, well done !
