I replaced my downpipe with a fancy performance one and took the old one to the scrapyard. Turns out the two catalytic converters on my old one were worth $180. So I bought an expensive bottle of whiskey.
I tell a lie, I actually bought some scotch. Ten year old Laphroaig.
The one thing to be careful with swaybars is that it can make the car oversteer/understeer especially in snow/rain. Oversteer in fwd cars is fun because you don’t want to let off the gas and transition the weight off the rear. I used to auto-x a dodge neon. I would pump up the rear tires so I could get the car to rotate, of course I had to stay on the gas through long sweepers or it would come around.
