Hey guys and girls,
I purchased an R55 full-system last week and decided to put it on over the weekend.
Anyways, the install is pretty straight forward so long as you read the instruction manual and have tools handy.
I won't detail everything about the install, but i did take pics of some of the stuff that caused me to and drove me nuts.
