Hello all, I am new to owning my 2011 E90 M3 and would just like some advice on exhaust setups that will not throw a CEL or cause other issues. I have been going over the forums for the last few weeks but honestly find the amount of exhaust combinations a little overwhelming and do not know where to start.

I am looking to get the best bang for my buck honestly with a budget being about 2500 for everything max. I have played with the valvetronic idea but also am curious about test and X-pipes. My main concern is I would like something with noticeable power, and increased rasp and sound overall over stock without causing a check engine or throwing codes. Any help would be greatly appreciated!

Respectfully,
