I have a cleanly removed Euro Sport Tuning muffler and tips removed of my 05 FWD s40 t5. I went with some black stainless tips and had the muffler removed. I'm assuming this could be of use to someone!
$250 obo trades welcome, short shifter, strut brace, RSB, +$ for wheels.
I don't see why it wouldn't be possible, you best bet with the s60, would be to either make a new flange, or use your stock flange ( if you don't mid letting the muffler shop cut-up your stock exhaust). Then just custom weld the piping up to the muffler, and adjust the positioning of the tips according to your bumper. This sounds like a lot of work, but if you find a good muffler shop it would probably run you around $100-200.
