128i performance exhaust feedback

Hi There
Anyone out there mod your exhaust to the performance muffler from BMW or the Magnaflow catback. Any suggestions would be helpful. I presently have the stock 2008 128i muffler system and thinking of changing it. Did you find any power difference after the change? What difference did you like about how it sounds after the mod? or didn't like if any? Which system is better BMW performance muffler or the Magnaflow catback system. Thanks for your feedback. Cheers!
