Buy it with the muffler. Much easier and cheaper to put in a delete pipe if it isn't loud enough for you then to buy a muffler because it is too loud for you. Beware of the VVT hiss if you are not running EFI live or the newest EDGE to tune it out. What year is the truck?

You will have a hiss at idle due to the vane position of the turbo until you tune it out with EFI or the newest Edge. Some people don't mind the hiss. I don't like it. I am running the 4" MBRP downpipe back with a 4 inch Magnaflow clamped in cat. Even with the cat the hiss is there.

5" will not provide you any added gain over the 4". Just a deeper tone. The 4" with no muffler no cat is plenty loud. Maybe too loud depending on your personal preference. That is why I would order it with the muffler and you can delete it later if it isn't loud enough for you.

Just a suggestion, you may want to put some details about your truck into your signature. Other members will be able to assist you better with that info.

What is this "too loud" thing you speak of?

Really not too loud at all (IMO) until WOT

Ha. I like the straight pipe tone, but if I were towing heavy on a long trip the drone would get annoying IMO. That WOT scream has me burning through fuel!

You have your hiss tuned out? That shit is annoying me.

I guess drone to some isn't drone to others. Some will tell you it drones at 60mph without any load.

Maybe the exhaust being further back from your cab on that long bed helps :D

Overly loud is a matter of opinion and personal preference. You could get it with a muff, then take it out if you want it louder.
