What do you guys think, Flowmaster 40 series or the Supertruck gibson exhaust?

 

I just put the 40 series flowmasteron my 04 4.7L Quad cab, and they sound great, especially when you start the truck.. there not to obtrusive and at 70mph there really quiet inside the cab. I removed the muffler and added the the flowmaster in its place so my end exhaust looks stock, but sounds great

 

Love the Flowmasters, I'd definately recommend them. However I don't personally know anyone with Gibson

 

Flows for sound and just about anything else for performance.

 

I love my Gibson dual exhaust. One thing to ask your self is, do you want it for performance or sound? Sound= Flowmaster. Performance = Gibson. Flowmaster has an incredible sound, but youwill not see the performance until you get into the higher RPM's. On the other hand, the Gibson is made for performance at lower RPM's and still has a gut wrenching sound, but it's not quite the Flowmaster sound.

 

GIBSON!
