My bother has a 2005 Volvo S60R that likes very much, I'm not sure what mods he has but as far as I know the mods are

3 inch downpipe/high flow cat
full 3 inch exhaust to match the downpipe
aftermarket valve diverter
not sure about the suspension but I know he has done a lot it
aftermarket silicone intercooler pipes
idk what kind of clutch it is but he replaced it
idk what else but he is not having luck with the boost cause he is only pushing 4lb

I hope that the people that i use their vids to make this stew don't get mad,
I sure they will be ok with me showing how awesome volvos are, I almost got a volvo before I got my Mustang so I done my research and I have yet to find a unlikable volvo owner I do have my eye on a Volvo polestar or a
R design.
