By replacing your stock downpipe with an upgraded one, you can increase horsepower, improve exhaust flow, and boost overall engine performance. In this article, we'll explore the benefits of upgrading your downpipe and provide tips on how to choose the best one for your vehicle.

Super informatieve film. Hier heb je echt wat aan als je wilt weten wat de opties zijn met voor en nadelen en de mogelijkheden om de CEL foutcode op te lossen. Hoeveel cel is een standaard kat?

[@psrparts]

Super bedankt! De originele katalysator verschillen qua cells, maar zijn meestal ergens rond de 800 cells

[@barthendriks8581]

Great explanation and it answers most questions we have with regards to getting (some of) the sound back in our OPF-vehicles. Sign me up for the 300cell DP as is seems to be a happy middle between sound and hopefully not getting a CEL (ie unlock via FEMTO or LEIB to fix it). Maybe a catted downpipe with an aftermarket axleback (while keeping the OPF-midpipe) is the goldie-locks zone between sound and staying emission-compliant? Keep the vlogs coming!

See you soon Bart ;)!

There is a difference in sound between 200/300/400 cel downpipe? I have an 540ix (dont find any videos on your page with 300 cell version)

[@psrparts]

The sounds varies, the 200 to 300 to 400 is getting more silent the higher the cell count.
