I would never spend big coin on ARH's without Ceramic Coating them, only way to make them last...
Specially if you're in a part of the country that gets snow, ice and salt covered roads in the Winter.
My track bud MGRAM just spent over $1k on coating his whole exhaust
from block to tips....ARH LT's and an MBRP CatBack:
Just waiting for our new transmissions to arrive from MGH to install it all at once
