Stainless steel downpipes with heat shields and 200 cpsi euro 5 cats for BMW 550i / 650i / X5 / X6 and other N63B44 4.4 V8 turbocharged motor applications include 550i F01 and F10 along with 650i F12. Must have flange connections between downpipes and center section of exhaust system - send in your VIN number with order in PO comment area of order entry. Changes to slip fit occurred 2012-13 models.

     Features:

  • Manufactured from high quality 3" stainless steel pipe for superior heat resistance and strength. These stainless pipes replaces the OE catalytic converters for additional power.
  • Be careful of low price versions of this style of downpipe. We had a lot of problems with fit and quality and discontinued selling these models. Our model is far superior in build fit and quality.
  • TIG welded and CNC machined flanges for strength and durability.
  • This increased exhaust gas flow from this reduced restriction allows for more power in the low to mid range RPM. Generally around 10-15 HP
  • Comes complete with O2 sensor bungs, braided stainless integrated flex pipe for better alignment , gaskets and bolts.

    Special notice!
    BMW made 2 different downpipe connections: flange and slip fit. Before purchasing you need to verify which connection you have. Look underneath your car where the downpipe connects to the exhaust and see if you have a bolt together flange or slip fit with compression clamp. This model is for bolt together flange connection.

Difficulty

I’ve had these shoes for a few months now. When I first got them, they were very painful to wear. I was wearing them pretty much every day but found them to be extremely tight. I thought perhaps the shoe just had to “stretch“ and conform to the shape of my foot, so I decided to give them a few weeks to do that. After a few weeks, they were still somewhat painful to wear. It was only until just within the last month or so that they have become painless to wear. So please be aware that you might find the shoes to be very uncomfortable when you first get them. Give them a chance to stretch and adapt to the shape and contours of your feet, though. The shoes are extremely lightweight and very flexible and bendable. They almost seem cheap in that regard, so I’m not sure what to make of that. I’ve never had a pair of shoes like this that were so flexible. I’m used to having a hard, rigid sole and an inflexible upper. The shoes do look very nice and seem to be holding up well. People have complained in their reviews that the stitching at the back on the heel comes undone. I haven’t noticed that with mine — yet. That is the only part of the shoe that doesn’t seem to be designed very well. Why put stitching in such a precarious place on the shoe? This is the first shoe I have ever seen that has stitching on the heel like that. But, as I mentioned, my stitching is NOT coming undone like many others have reported. PROS: 1) The shoe seems to fit comfortably after a couple months of extreme discomfort. Still not the most comfortable shoe overall, though 2) The shoe looks nice! CONS: 1) The shoes seemed very tight when I first got them and stayed that way for a couple of months thus ensuring extreme discomfort and pain when walking in them. 2) The stitching in the heel is a bad design! 3) Due to the shoes being extremely lightweight and flexible, they almost seem cheaply made. RECOMMENDED WITH HESITANCE

Nice-looking shoes
Size: 7.5, Color: B-black
I really like the look of these shoes. They can be worn for more casual look or more dressy look. When I first tried them on I considered returning them because they were a little tight in the width. I wore them for the first time today. After only 2-3 hours of wearing them I could tell that they stretched some and weren’t so tight across my toes. They were comfortable too. I am generally not hard on shoes so hoping they will hold up well.
