Perfect fit
Was a little difficult to put on but got it on didn’t even know it came with exhaust tips great value most definitely recommend
Excellent will do business with again
Part came in as described and the quality was actually pretty good for being an aftermarket non oem part. Would highly recommend if you are just trying to see if you like it or not and it is sturdy
I encountered some difficulties in my own installation, but it went smoothly. It looks good. happy
