i like the interior…

the AA exhaust is prone to crack on the hangers so you may want to take a look at the welds there to ensure they are not showing any signs of fracture, if you know somebody who can tig i would have them go at them from the other side as the penetration needs some work from what ive seen

i imagine your on m3forum ?
