Cat Back for 4.7L

Recently purchased my ride and looking to improve the exhaust. I might as well go ahead and do a complete Cat Back rather than upgrade just the muffler. I found this system during my search. Anyone have thoughts on this?

http://offcamberfabrications.com/ind...&part=S5504409

I am looking to add performance by letting the engine breathe better. I would like a nice sound that isnít obnoxious or too loud. I want to avoid the droning noise I have read about some exhaust systems.

Any advise welcome about this exhaust or any other cat back.

Thnx

I plan to use the AFE cold air intake

I want to match it with a quality exhaust that provides performance without being excessively loud.

Thanx Hummer recovery team. How did the Borla effect sound quality inside the vehicle?

Is this the system you are referencing?

No sense pushing more air in if it can't get out. Intake mods and exhaust mods should go together.

That cat back (MBRP) is really nice. My buddy just installed it on his 06 Hemi Commander. Not sure how it would sound on a 4.7 liter but I bet you would be happy with it.
