i'm from ontario canada so i wouldnt know,if you wanted it done you might have to get it done at a muffler shop, cuz it's illegal to remove the cats here anyways. my dad got dual 2 1/2 pipes on his 79 f150 from header back for $350, cash deal with mufflers and tips,
Ps what muffler did you get with the american thunder, there's 2 kits one with a 40 series and 50 series or delta or something (quieter then the 40's anyways)

illegal and a $10,000 fine for you and the shop who did it
don't do it. the stock exhaust is good for 400 hp easily.
you'll get some better sound...but most guys seem to lose TQ, and then you have to deal with O2 sims are a programmer to turn them off
