whats the loudest dual exhaust i can buy? 05 4x4 screw 5.4l... borla, flowmaster etc?

 

True dual straights with no cats and long tube headers. It's also one of the trashiest sounding.

 

x2!

 

X3. The loudest cat-back? Flowmaster Super 10 kit from eBay ( its a shop made seller using junk pipes with Flowmasters loudest street muffler.

Loudest quality cat-back that won't rot out, and wont kill exhaust flow, and come with a warranty? Corsa DB Series.

 

Loudest is just straight pipes with no cats like the other people said. Sounds bad and is probably unbareable for a daily driver but it's loud

 

Flip the headers upside down and run them through the hood. Nice and loud.

 

Never buy an exhaust based on being the loudest. Wouldn't a little sound quality be nice too?

 

There you go

 

True duals with Magnaflow SS X muffler and 3" pipes. Nice out loud. By loud I mean low-end loud. It whops very loud but it's so low you don't hear it in the cabin:

Startup and Idle - Street Level

Low Speed Cruise - Inside Cabin

Takeoff - Inside Cabin

Takeoff on Freeway - Inside Cabin

From a Dig - Street Level

High Speed Flyby - Street Level
