It's not that hard. I say go for it! I like the performance aspect of it but also the sound of it is real good. I just added a crossover pipe today to my true duals and it sounds even better!

howd you run your dual exhaust?

would i just have to get two cats, and run like 2.25 or 2.5 pipes all the way back with a cross over and two 50 or 40 series flowmasters or something like that?
