Take it to a local muffler shop(not Meineke or a chain store) They will know what to put on when you tell them the sound you want. Magnaflow, Flowmaster, and the like are over rated. I used glass packs on my 2002 Chevy and took off the catalytic converter. It sounded AWESOME. Should cost $250 or less to have dual exhaust put on.
i agree with you on magniflow but not flowmaster. magniflow is overrated. if i wanted a glass pack id get a 20$ chery bomb not an overpriced glorified glass pack(magniflow). flowmaster on the other hand is a totaly dfrent kind of mufler. it all depends on what type of sound you want. if you want the glass pack sound they all sound the same magniflow is just overpriced
my truck has the 02 senser before the cat so i have no cat without any problems, but if you have any sensers after the cat you service engine light will come on without a cat... something to think about before riping out your cat... and it cost me 600 for true dauls with 2 flowmaster 40s and an h pipe and tips and all.
