Just recently got my MD catback installed and now my rear end looks like ***. My previous setup utilized quad tips which required expanding the exhaust cutout on the rear bumper. Going back to dual tips makes it look out of place.

I was thinking of getting an exhaust shop to possibly mod the MD exhaust to fit some quad tips, but I don't really like the idea of cutting up my brand new exhaust. So my other options are to replace the rear bumper, or purchase the rear diffuser from AutoKitsX.

I wanted to see if anyone here has experience with this diffuser. How was the fitment and how's the quality?

I had their diffuser on three of my cars fitment and quality was great! I also had their CF hood on my coupe and CF side skirts on my G37 Sedan.

 

I was looking Tollboothwilley web site for the engine undertray and they have a rear diffuser for the sedans.
