header/exhaust install DIY?
Who has installed their headers/exhaust themselves? I'm considering bolting on the dynaflow long headers and MBRP exhaust myself but would rather avoid any complications while installing or issues post install without having a tune, et al-- so I'm thinking about having a tuning shop install for me.
For those that have done their own install--
How difficult were the headers to install? Was there a great deal of labor involved? Was it driveable pre tune?
What about cat back exhaust install?
