Hi guys
I recently added a custom 76mm downpipe to my s3. It has really made a huge difference in terms of power. The car is much more responsive without the cat and sounds really awesome in boost.
After a while the emission control light came on. Is this something to be concerned about...
Hi Guys. I hope all is well. I bring greetings from South Africa. You guys really have an awesome site. I drive a 2009 3dr s3 and I look forward to some excellent advice from all the s3 maestro's.
Cheers!
