I'm ready to order a corsa cat-back for my 99 rt10. I plan on sticking with stock cats for now, but I may upgrade those later.
My question is should I order the 2.5" inlet, or 3" inlet cat-back? Considering that I may go with 3" cats in the future, but need to fit the setup to the stock 2.5" cats for now.
