My question is how hard is it to remove/revert to stock? The reason I'm asking is that I plan on upgrading my car in the next 1-2 years, so not going to keep it for long, but still want to have some fun in the meantime. When I trade in, I would trade in with the stock exhaust. Does anyone know what it takes to revert?

Where as the m235i and mpe has a straight entry.

So to install you would need to cut the curve on your oem 228i mid pipe.

Therefore the only additional part you would need is a new mid pipe.

(i think)

See this post. The problem is inlet diameter. The solution: have your muffler shop fabricate an adapter that is welded to the MPE, then use clamps to attach the MPE to the midpipe. That way, you can revert to stock without cutting anything; it'd be a simple slip off-slip on operation.

Keep us posted!
