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:

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?
