I use Spiral-flow mufflers for resonators. It's about 100hp shot judging from the dyno runs. Yeah I'm the first (and only that I know of) into the 13s with a Titan. No big deal - there will be others.

Just the box. As often as it rains here I'm paranoid about sucking some water from minor street flooding. Since that's not the only intake piece, though, I may re-think that.
I do remove the tailgate, spare, all utility bed stuff, and try go get there with no more than a 1/4 tank of gas. It helps.

I probably missed this in some other thread, but what's your reason for running the spiral flow mufflers instead of straight pipes in place of the OEM resonators? Or am I misunderstanding you and you placed them elsewhere? I can't seem to find it now, but didn't Jet Tech remove his oem resonators for straight pipes?
I remember reading an interesting thread on this, and I was contemplating going this route, but wanted to see what people's opinions were after putting some miles on such a set up.
I went with them due to the fact that they are guaranteed to reduce noise by 5-7dB. That might not seem like a lot but the Banks was about as loud as I wanted to go. I think it is a little more noisy but after talking to Pciley on his striaght pipes, I decided that I wanted something in there rather than just straight-throughs. The stock resonators are 1.5" in diameter which is exactly the same diameter of the pipe going through the spiral flow. However (obviously), the body of the Moroso allows the rest of the flow to get through. I will grant you that these most likely don't flow as good as a straight pipe but I was willing to sacrifice a couple of hp to keep it a little more bearable inside the truck. In fact, I'm thinking about putting one of those cone-things (vortex?) in it on the Banks muffler exit and ditching the coffee can tip for a 90 degree bend to make it look more stock. Several people have also said that removing the Banks tip makes it a little quieter as well.
I compared several race mufflers but only the Morosos were guaranteed to hold the noise down to an acceptable level for almost all racing associations. Most of the straight "bullet" type mufflers don't do that. In fact, I wouldn't waste my money on them as a sound reducer and just run straight pipes if given that option. But that's just me.

It is a good deal quieter, at least on the 4x4's that don't have the resonators. I took off my megaphone tip and cut off the short 3" to 4" transition that it clamped to. Then I clamped on a temporary 3" extension and it does definitely help. I ordered a 3" to 3.5" Banks tip that is in route to me now, due here Wednesday according to the tracking data.

Does anyone know if we can order the Banks with a 3.5" tip instead of the 5"?
Head, I did a nitrous search for this site and it seems that you're the only guy with the balls to brave it. Can you tell me the kit and part numbers of the other items you used? What type of auxillary pump did you use? Inline? If you used one at all...I have tons of questions as far as how you did it 'cause I ain't found a kit out there yet. Please feel free to PM me if you'd like. Also, have you found a nice set of slicks or drag radials and rims to try?
My best times, which include removing the rear seat, spare, tailgate, floormats and all lint I could find (oh, my truck STILL has the stock exhaust, but with the air box mod and I have run C12 with O2 simulators....got addicted to C12 racing the Buick GN.....was a 14.7@92......I wish there was a way to hook the Turbotune up to this thing or change a timing frame or two.) I'll bet someone....like Jay Carter, hopefully, will hack this ECM....soon. I could type forever, but I'll prolly have the average Joe wondering.....
