I had a similar idea for my exhaust, I just didn’t like how low it would hang. Do you have a picture from the rear?? It does look pretty cool tho, the shinny muffler looks dope out back.
I (think I) finally isolated the world's most annoying and persistent squeak in the driver door, though all the times I've removed it and reseated the door panel finally caused one of the plastic hooks the panel hangs on to break off. Fortunately it still seems to be hanging there rather solidly.
