435i akrapovic link pipe with mpe
Hey guys
I recently traded in my 135i for a 435i, I added the mpe and mppk and I am looking into adding the akrapovic link pipe that will replace the mid pipe and resonator. See image below. I have enquire at BMW if the pipe will be compatible with the mpe, but its looks as though it should be from the images. akrapovic is bmw approved and thus I get to keep my motorplan.

My question is has anyone removed their resonator/middle box on a 435i or similar. As you can see in the picture, its a very small box. What were the results?

My goal is to increase the volume of the exhaust. I had a similar setup on my 135i which was loud and awesome. see here:http://www.bmwfanatics.co.za/showthread.php?tid=48763
there was very slight drone at certain RPM's and gears, but nothing bad and the increase in sound was well worth it.

From what I have read, the dual pipes of the link pipe eliminates the drone you would get compared to a straight pipe from cat to back box. Any opinions etc are welcome.

Hey guys
So just some feedback. I decided to remove the resonator. So, in summary I have the oem cat, then a striaght pipe to the BMW MPE. It sounds great, zero drone, its louder and more throaty and i got a slight improvement in my fuel economy. I used power pipes and they did a great job. Here is a clip:

RE: 435i akrapovic link pipe with mpe
Sounds great.

So have you cut the resonator out and welded another piece in place to make it a straight pipe?
Or have you replaced the entire mid pipe with a new piece?

I've done a decat with the oem mid pipe into the mpe. I'm scared of a drone if I change the mid pipe

RE: 435i akrapovic link pipe with mpe
That sounds sick.. So it is basically a straight pipe from the stock converter to the backbox? I like the throaty sound.. And this is just revving, must sound sick on the road.

Looks like Power Pipes there in Fordsburg? Next to the rail tracks?

Correct straight pipe from cat to back box, that's the one. very throaty, but makes more crackling similar to the a45 when the pipes are cold but engine is warm, then your typical 435i 'farts'. Overall, very happy.
