It's been a while since the F20 M135i was launched and we heard only great things from everyone. We even reviewed the car a while back and were also impressed with its overwhelming performance.
Get this though, the guys from Milltek released an exhaust that will simply add around 30 HP to your car's total with a couple of tweaks and tricks. Their system is made completely out of non-magnetic stainless steel and measures 76 mm instead of the stock 80 mm.

It might seem like a bad idea but the numbers the car returned on the dyno say otherwise. The guys claim that the stock M135i returned 322 HP and 344 lb-ft (466 Nm) of torque on the dyno as stock.

After installing the Milltek Performance Exhaust System and fiddling with the ECU, they got no less than 355 HP and 416 lb-ft (564 Nm) of torque out of the 3-liter turbocharged engine.

That was for the Stage 1 upgrade. For Stage 2 they went with Milltek's 200 CPSI hi-flow sports car/downpipe combo and, after tuning the ECU to correct parameters, got the Bimmer up to 373 HP and 446 lb-ft (604 Nm) of torque. Impressed yet?

You can find all these parts and even more info on their website, in case you want to take your BMW F20 M135i to the next level.
