Exhaust replacement

I have a 2003 TBlazin'... Many mods including billet grille, billet bowtie, kenwood dvd player with 7" screen, 2 JL 12w6v2's, JL 500/1, JL RBC-1 bass remote thru the middle of the traiblazer logo on the inside, Viper alarm system(remote start), Passport 8500...so on.... but i have a borla exhaust system on the way. including cat. and back to the tips... has anyone pulled a factory exhaust off yet.. If so can i get a quick run through, or am i better off having a shop do it?
