Downpipe Comparison

With all the Black Friday/Cyber Monday sales going on I've been considering pulling the trigger on downpipes for my 550i. As I search, there are several different manufacturers with generic downpipes priced in the $200-300 range and then some more well known manufacturers ranging from $1200-1500.

The big question is, what makes one, regardless of price point, any better than the other? They're stainless, catted or not and the length and pipe diameters are all the same.

If you have a set, what made you go with the brand you chose?

Thanks!

What generic ones are you referring to? The ones on eBay will not fit.

There is someone here who tried generic DP's and they don't fit. I personally wouldn't gamble with potential boost leaks due to improper fitment. You could find a used set of one of the proven brand DP's.

Haven't pulled the trigger yet, we have emissions here in MD so I need to ensure the catted DPs will still ensure I can pass emissions testing.

You're going to want a software flash after installing them, so just make sure your tuner shuts off the CEL for the catless and you'll be fine.

You will pass emissions as long as you get a tune to put your monitors in ready State. As long as they don't visually look for cats your ok. Depends on the emissions laws by you.

In MD, they connect to the OBDII port to see if there are any faults and then sometimes stick the probe in the muffler tip to monitor gases. No visual inspection here.

He is non-LCI, he couldn't get a flash tune for that anyways. (no love for our N63 DMEs)

Interesting to see you are developing your own dps. Since you are indie are you going to offer some type of cel defeat?
