Hey guys. I don't trust my local BMW. I said I was worried the pipes will stick out too far with the stock diffuser. They then said to buy a performance diffuser to solve the pipes sticking out too far. I then noticed on my quote that they charged me for extension tubing lol.

Can I run the MPE with stock diffuser without the exhaust sticking out too far.

Pics would help.

Cheers

There are two different MPE options just buy the right one.

Thanks.
I love how the parts department doesn't tell me this. Drives me nuts!

You can use MPE for stock diffuser w stock diffuser.

You can use MPE for stock diffuser w M diffuser if you use the extender pipes.

You can use MPE for M diffuser w M diffuser no extender required.

The only "problem" situation requiring fab work would be if you wanted to run the M diffuser MPE with stock diffuser.

If you want max flexibility with no rework required get the one for stock diffuser now. Then if you add M diffuser later you just get the extender pipes.

My car came with the MPE and stock diffuser, when I put the M diffuser on I just slid the tips back 5/8" and everything fit perfect.

Is yours a 240i? If yes how do you like it? I'm getting mixed info on here that you can't really tell the difference with the 240i's double resonators.

I realize there is no performance gain and I don't care about that, I buy exhausts for sound.
