I just bought an 07 silverado and wonderin what exhaust system i will get the most horsepower and best sound out of...right now i am looking at the Banks monster system and also their manifolds..what do you think about it or have you heard anything bad about it??

Flowmaster original 40 - there have been a few threads on this if you search you should get some good opinions.

Deff got to say on exhauts thats more persal taste
i dont think that flowmaster sounds good at all
im more of a magna flow kinda guy not as loud but deff got all the groull you want
but depends on where you want your gourlllll the most hwy or city
i do more hwy and city so the groulll that i get from magnaflows 40 is best
but flowmaster i have to say all the 40 60 series iv seen and had has had a hell of a groulll at
very low RPMs but how often are you running at low RPMs
most time prob. at mid range rpms

It all depends on personal prefrence, as far as sound goes.They all produce about the same HP gains. Look up the muffler you want as a sound clip on you tube.
