The full DIY for this is already done, (http://www.2addicts.com/forums/showthread.php?t=975574) but here are a few hints.

1. There was a statement that it took a lot of force to mount the new diffuser and get the clips to engage. If you are just pushing in then that is correct. Here is the trick, push in AND up. If you push straight in, it does take a lot of force, if you push in and up it is not bad at all (maybe 25 ponds of force, vs needing at least 100 for straight in.)

2. If you are adding the diffuser but not the m-performance exhaust, then you have to install the tail pipe extenders. This requires cutting the stock exhaust. Be warned that a standard exhaust pipe cutter will not cut this magic BMW metal. I tried. Be ready to use a sawzall or cut off wheel. Here is a link to the details. http://www.2addicts.com/forums/attac...1&d=1411568438

3. For the record the original exhaust tips will fit the extenders and m-performance exhaust. Takes some force, but they look good.

Good call on the push hard, in and up....I thought mine was defective when I first tried to install it......Took me a bit but it went

Nice good to know supplemental tips.
