Are these going to be an item you keep in stock or just limited production and only available for a while? Would like a set but have a few other things I need to spend money on before more performance mods.

We don't keep downpipes in stock but are ready to be made at anytime, its about 1-2 week production time after payment. This is the new set price for downpipes.

How much louder would my CL600 be if I retained the stock exhaust and put in your cat less downpipes? Also how much whp would I see without the tune being adjusted?

At what point do you feel its necessary to increase the exhaust size? Is it safe to assume with your down pipes and upgraded stock turbos the remaining stock exhaust will still be sufficient? I'm just thinking of possible future mods. Either way the point of connection still remains the same size on the stock turbo housing, its just a matter of if increasing the entire way back is even worthy of any gains.

I did 3 inch on my whole exhaust, but I plan to swap out the swap out the turbos at some point, but I may have to change the down pipes again, which is why I v banded my whole exhaust so I could drop sections if needed instead of constantly cut and wield.
I don't know if its because the pipe is bigger, or the there is less back pressure or both, but the the turbos spool up sooo much faster and the torque feels even more then just with a tune alone

Sounds good, I can understand going for a larger exhaust if you wanted the cutouts/ dumps before the mufflers. I only intend to do the downpipes for now. I don't think there is a huge benefit with such a small increase in diameter. But it does make sense in your case to avoid having to cut and weld everything in. Do you have any before and after dyno graphs? It would be interesting to see what is gained though out the curve, not just peak.
