Anyone know if they are the same size as the c300 sport ones?

 

yeah only difference is the metal bar in the middle

 

thanks

 

AMG quad-pipes however will not fit into the openings of non-amg cars, just an fyi
Originally I thought the c450's came with the AMG quad pipes but no, like topsider said...just the extra bar down the middle of the opening

 

The real quad pipes would've been nice on the C450, but the AMG owners would have a fit.
