Anyone? N52 Performance Exhaust Mod

I been looking through the forums and can't find a proper way to do the PE Mod on a n52 but found plenty on the n54. Has anyone done it to their car or have a video of how it sounds? Any help would be appreciated

What do you mean by performance mod?

Easiest way for more sound is to cut off your muffler. You can try to gut the muffler out (there was a thread on it few months ago), but I never heard the way it sounds. You can also do magnaflow. However, nothing beats BMW PE.

Yeah gutting the muffler is the PE Mod but I didn't see anyone do it yet for the e90 n52. I was hoping someone might have a sound clip otherwise if someone has a used one laying around.

its been done before, i plan on attacking this a different way than others though. gut the muffler, pick one thruway point & straight pipe to the tips, basically mimicking the 335 & me method. not going to confuse myself with all the bends like everyone else did

I attempted to do it one time but after cutting it open I wasn't able to use the square piece that I cut out. Since it's sort of flexed when bmw makes it. It was smaller in size when placed back on, and when I looked into it looked like a pain in the ass to have to tackle. Then I realized that I needed to cut the other side open as well to be able to complete the weld of the new pipe (deleting the perforated section). Decided to scratch the project because the whole point was to make it look oem stealthy but with having to cut both sides and not being able to replace it back with the old metal it just seemed more plausible to get a glasspack lol and go another route.

I'm curious on how mmw used to do their exhaust's utilizing the stock ones. It's too bad they just flopped and disappeared. Headers and exhausts were so sweet back then

I was going to do this, but once I pulled my muffler off and fired up the N52 I absolutely loved the sound and decided to just go for a muffler delete with some new black chrome Cyba tips. Sounds amazing and looks great with the tips.

I would suggest going this route in order to save the headache that might come with trying to do the PE mod!

Just my $0.02! 👍
