$800 Quad Exhaust With Bumper Diffuser

Here's a quick DIY for a great looking quad exhaust with a good sound for < $800 total.

Parts list:

$250 Used oem echaust (look on the classifieds on the forum)
$150 Alibaba Quad exhaust diffuser for F30 435i - Link
$50 Dual tip U Power exhaust tips from Amazon - Link

Have a local shop do the exhaust mod via this thread:
https://f30.bimmerpost.com/forums/sh...d.php?t=819125

The exhaust tips are a direct weld on and fit perfectly.

What muffler is this? The sound can't be much different with just new tips.

The sound is fantastic. You modify the exhaust box via the steps in this thread.

I will post a video of the exhaust in the next few days.

Another benefit of this option is that you keep the exhaust flap.
