Hello all. Just bought a 2002 Volvo S60 2.4T with 68k miles in very nice condition. Had my local Volvo shop look at the car with favorable results. Brakes were at 90% rear and 70% front and the car had new Pirelli P6 tires. It needed a top mount and they did not have record of the timing belt being done. I did the top mount with newer square plus model and also did the bottom trans mount just as precaution. I also did the timing belt kit along with fluid changes of engine, brakes and transmission. I should be set for a while now. Drives very similar to my previous Saab 9-5s. I have seen 2 items that kinda interest me. 1st is the OBX catback exhaust and the other is their catless downpipe to make a matching pair. Would I need to tune too or am I fine without. I am familar with the O2 spacer that would be required. Also, anyone have the catted CNT downpipe? Wondering if it necks down to 2.5 to match the OBX catback 2.5 flange.
