on my motorcycle, repacking of the muffler is something u have to do time to time. It's not the most fun thing to do, but u gotta do what u gotta do.
I never heard about people repacking the car mufflers though. I guess cause u can get a cheap muffler and just weld it on at a muffler shop
cheap wheels are available everywhere. Usually, u can find cheap wheels on ebay.
although i'm very poor, but i still like wheels with great tags on. Like, SSR Professor Wheels.
