ECOTUNE BMW E46 320D Decat Downpipe

I bought this for my E46 320D 2004 Saloon and it was a direct fit. Taking out the old one was the main problem but fitting this back in was perfect. It lined up everything correctly and fit how it should. The item came how it should, had nice weld beads on it and everything looked the part. I noticed it didn't come with any original mounting parts but I guess it didn't need it as once it's all screwed in, it's all held in place and it's a lot lighter than original. I would suggest buying new bolts from dealership or Ebay as the old ones are probably on it's way out - this goes for the mid pipe side and the turbo side of things.

Moving on to sound... so they say it doesn't make a difference and it probably wouldn't make a difference if you had everything else standard, however this was not my case and I pretty much have a straight through. I can say that it doesn't drone which I'm thankful for but it definitely doesn't sound like a diesel. Its loud and does get a lot of attention but it suits the look of the car. It's not obnoxious but its loud when the turbo goes into full boost which helps with performance. There is a massive difference in free power after doing this. What I mean is that I can feel nothing restricting my engine anymore or my turbo. Temperatures of my turbo has dropped lower too which helps it run cooler and more efficiently.

I'm sure economy has been affected however, expect it to drop as you're gonna put your foot down to hear the car open up xD

So theres questions about MOT and will it pass. Now they will not find much difference within your emission test, however on the visual check they'll be able to see your turbo cat has been removed. I've remedied this by purchasing some flexible heat shield and temporary covering the visual sight of the cat so they can't see if it's still there or not. However do not take my word for this method, it has just worked for me and you should always follow legal rules for your car to be road worthy.

All in all it's been great having this downpipe and I appreciate the communication you guys had with me and keeping me updated with everything. I know it was difficult during Covid-19 but still came fairly quick. Thanks again guys and hope this review helps anyone who comes across it.
