Yes.
Obviously, you should do this now so that you don't end up paying to paint two bumpers (stock AND m-tech in the future).
To restate what everyone else has already said:
- The m-tech rear bumper for both the 328i and 335i are identical, except for the diffuser.
- You can buy the 328i m-tech rear bumper now, and keep the stock 328i exhaust and stock 328i diffuser until you are ready to change the look.
- When you are ready, you can simply purchase a new diffuser made for 335i m-tech rear bumpers, and replace your 328i diffuser with it.
- In addition to changing the diffuser, you will need a custom exhaust setup if you want something that looks like a 335i.
I did this exact same thing years ago. I bought a 328i rear m-tech bumper and later replaced the diffuser with a carbon fiber one made for a 335i. Then I bought some quad tips, got custom piping done, and now my rear end looks like this.
