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 qualtiy.
- 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.
