So I have the opportunity to purchase (new of course) the Magnaflow Exhaust 16537 including tips and all for $600 dollars shipped!! It was originally around $840/shipped. I have a euro air box with a k&n cone filter, my BMS PBX should be here any day now.. My question: as the title states, should I do it?! I'm not looking for anything crazy loud just some nice sound at a decent price. I've thought about the remus but that's only the muffler for almost two hundred bucks more than where I'm at right now..

Does anyone have experience with this set up?
How is my air box and PBX going to play with my exhaust?
Power increase with all three (PBX, Airbox, Exhaust)?

I know I don't drive a 335i but I'm just trying to utilize the most out of my NA engine...

Thanks for the input
