I definitely like Whitbread's downpipe better than others I've seen (except for the Unobtanium one that's like $1500...). Are you having them do everything from start to finish? Or are you planning on DIY'ing the parts install & sending the ECU for a pre-made tune elsewhere? Do they have a Dyno to do a legit tune? Or do they flash a pre-made from someone else? Been researching their "Hydrid" fluid dampener vs the brand name Fluiddampr unit; I like the idea of a "hybrid" design on the surface, but I also like the solid metal design of the brand name unit for long term reliability / durability.

Would be nice if they've got in-house capabilities for ECU coding, as they might also be able to delete out all the emissions sensors & components you often have to leave in the car & plugged in to prevent CEL / a bunch of hidden fault codes. Would also be pretty damn cool if they could redo the glow plug control to not activate once the engine is running, as according to BMW literature, this system does a bunch of activations during normal driving depending on engine / coolant temp for emissions compliance & DPF regen, as well as when the engine is off & detects the presence of a key in preparation for being started. Doubt this is possible, but it would be nice in order to bullet proof this system

Let us know how the delete goes, as I'll be doing the same using their downpipe & possibly their fluid dampener once the weather warms up.
