flowmaster or magnaflow for a 04 chevy avalanche?

[$FRA@NCI$CO$]

which would be a better sound for my chevy avalanche and give it more horsepower??

Flowmaster for sure they sound great on anything and add a few horse power.

Flowmasters too loud, too much irritating drone, especially in an enclosed cabin SUV. Maybe not so bad with a pickup, but I still think Flowmasters sound too loud. A nice SUV should sound strong, not obnoxious-ghetto loud like a mud truck. Magnaflow is nice, I'd also consider Gibson. I also have an 04 Avalanche, I'm putting a Gibson on it.

depends on how loud you want it to be flowmaster is generally louder than magnaflow and if you want horsepower with all the new cars being controlled by computers you have to reprogram/chip your computer in the vehicle otherwise you won't gain the horsepower like how it could have for the new exhaust you'll just get a few extra.

take all the plastic off your crappy avalanche and then you have a real truck, even though its a chevy.
