Akrapovic, SuperSprint, Eisenmann, Remus, Borla, Dinan, they all make custom exhaust systems that will change the way you perceive your car forever.
However, their products are extremely expensive. For example, an Akrapovic Titanium Evo system for your M3 will set you back at least $6,000. Sure, it will give your car 22 extra HP, 34.7 Nm (25.6 lb-ft) of torque and will make it lighter by 24 kilos (52 lbs) but it's still six grand.
For those that love the way these exhausts look like at the back, under the rear air diffuser, European Auto Source found the perfect solution: Exhaust Tip Upgrades, more exactly 80mm stainless steel pipes that are fitted on the stock pipes of your M3.
They are riveted on, the same way OEM tips are so you can go back to stock at any time. Furthermore, you can choose the length depending on how aggressive you want to your car to look and you have a choice between brushed stainless steel and black thermal coat finishes for only $250.
