Hey, guys, I'm a former e90 owner and newly e60 6mt 550i one and given this forum gets way more traffic wanted to ask your opinion: I'm about to do a quad setup on a stock 550 bumper(non m) for now and then m5 replica and I'm torn between the tips style: single or dual wall, 3" or 3.5" and staggered or not? What do you think, I know it's a personal preference, but want to see what people think. Thank you.
