Does anybody have a link to purchase the kit for this option. My S60 T6 has the normal end pipes and I want to purchase the quad ones shown in this photo but the parts sites are kind of confusing as to which part#s I need to buy.

By the way, did you also drive the T5? Is the extra $5K and AWD penalty worth it?

 

It was definitely worth to me to get AWD and the additional power. I also got the Polestar option that gives you a little more HP and more torque. It's been a blast to drive.
