fitting wasn't perfect

Driver side of the axle back isn't straight and I did everything I could to straighten it out. It's not as noticeable unless u stare at it. And also both of the muffler tips were to small. They would not go in the axle back so I had to do a minor modification of my own and opened each of the 4 corners up with so channel logs. Sounds great tho!! It's more on the quite side but still pops! So far I'm loving it!
