I installed this Invidia Q300 axle back exhaust on my 2011 Lexus IS350 AWD and it fits perfect, looks great and sounds great too. The only thing you will have to do when installing this particular axle back to fit perfectly is to change the two rubber hangers that go near the mid pipe where the axle back connects to the mid pipe. The factory rubber hangers are too short and make cause the axle back to hit your rear differential. Just have to get longer rubber hangers and your done. Any auto parts store should have them in stock. I purchased mine in my local Advance Auto Parts. You may have to look through there inventory in the back to check different sizes. Hope this helps.
