So I followed a 335d touting just like mine down the M1 today. He had a pumped up exhaust and diffuser to allow the twin tear pipes. I looked very nice.! So I was quickly spending money in my head when I stopped and thought what is the benefit of this mod besides looks? Quick Google suggested the AC Schnitzer variety is 2k. That's a lot to look a bit more sporty?!
Do you get any performance gains on a 335d for all that cash?

Use 340i back box, will be a lot of free - very cheap ones around as they change to the mperformance one.

There won’t be any performance benefit.

No performance - just looks

sounds like a massive waste of money...?

No performance gains, just looks and slightly better noise. But mine cost £400, not £2k.

This is more like it! So how do ACS justify 2k?
What parts have you fitted to yours please is it a 335d? Any pictures? And any advice about how this impacts on BM warranty all greatly received

As mentioned a custom exhaust from any local specialist circa £350-400. My f36 is booked in on the 6th Nov

the ACS option is a complete backbox replacement, it serves for looks and also continues to silence the DPF regeneration but sound output generally unchanged on the diesel.

the £325 option * exhaust work only* would leave you with dual split pipes straight through and no backbox, offering a slightly throatier idle sound, no noticeable performance gain but this option will make the car quite droney when it is doing its regular dpf regen so bare this in mind aswell.
