Has anyone ran an A3 TFSI or an S3 with a 200cell sport cat and the standard exhaust?
Did it make it quicker? Did it sound different? And finally will this pass the MOT and what about CEL lights?
Also do you need to upgrade the downpipe too or just the cat?
I want a BCS Powervalve cat back but they won't do that individually unless I buy a 200cell too, I can't afford to buy everything at once.
Thanks
