Yeah man, I used axle stands when I fitted my Greddy evo4 cat back last year. It's a bit of a pain in the arse because your squirming round on the floor but it's not too bad. I found the 2 spring bolts that attach to the cat pipe the biggest pain just because of ground clearance but it on now and nice and load 🤣🤣 don't forget a bit of WD40 too mate, just helps the rubbers a long a bit 😊
