I have a stillen axle back exhaust that I had on my 2013 Nissan Maxima. I now have a 2016 Nissan Maxima and am wondering if it will fit. It looks like it should. The other thing is the 13 had a gasket between the axel back exhaust and the y-pipe, and the 16 doesn't.

wondering if anyone has done this or has any insight?

I've tried the 7th gen borla catback on my 8th gen and couldn't get the muffler to work. I have to redo the hangers and the mufflers angle, i doubt they will work. I'm selling my borla catback for the 8th gen if you're interested.

Just an FYI, Stillen currently has 15% off on some items - expires 10/31/17. The axle back exhaust was $527.63, save $79.14 - comes to $448.49.

OP sell your 7th gen axle back set up and buy the correct 8th gen set up. Or go check out the resonator delete thread here... sounds pretty impressive to me.

I have read good reviews on Magnaflow exhausts. You might want to check it out.
