Akrapovic Pipes
 
Akras new system features a new layout with two central link pipes replacing the single stock pipe, a new muffler design, and carbon fibre tips. The dual-mode ECU-controlled valve exhaust from Akrapovič offers stock-level sound at normal cruising, and a deep sporty note when driving the 435i spirited. The Akra system replaces stock from the cats back.

Akrapovic claims a 7 hp bump, 1.8 lbs weight reduction and 8 lbs of torque gained.

I never liked how some of the akra exhausts had the carbon tips

they are a pain to clean.

I always preferred titanium tips. But since BMW's have black diffusers, the carbon tip does help it blend in more. Still prefer titanium:

Great system, great sound...$3000 for a cat-back is out of hand, though. I'll take my 2 hp gain and very good sound with the mpe axle-back and save $2000.

Indeed and good point as well. Akras are really more of an aspirational purchase ;)

What other aftermarket pipes are out there?

posted this in the wrong section before....New M performance muffler and tips installed last friday.... Looks awesome with the engraved ///M's on the chrome tips. From the outside, I immediately heard the different more seductive "pitch note" of the burrrrrrr. My friend punch revved the engine a bit in park and I was BLOWN AWAY by the sound and gurgle by standing on the outside and it hasnt even been broken in for 1000 miles. Although I couldnt really hear a difference or droning while driving with the windows up.... with the windows down, it was very distinct. I could also tell others can hear it from their cars because how suddenly more cars tried to "tempt me to race" them that night than the entire month i had the car.

The parts department warned me that over the first month or so... The exhaust is going to become MUCH louder and MUCH deeper, and in idle hearing that wha wha wha with its gurgling. I just hope i can hear it a little more than i can now in the cabin in a month. It would be nice for me to share the experience of the sound of the muffler with everyone else on the street! haha

It's worth it for the amazing sound and baller status. Some people who understand exhaust systems do get custom setups made which saves a lot of money, something to consider.

how much did the setup cost BTW? Were you able to order it as a factory option or was it an accessory you picked up from your dealer?
