Darren just about any exuast will pop when revved or engine braking. Mine does and i have a dumped tip, and just about every exuast ive heard will do it.

How is the power?

 

I never did get around to making a baseline dyno run... If you're familiar with SpikeTV's show TRUCKS! they did a show on power upgrades for the 04+ F150 and they did a baseline on an 06 FX4, so I'm going to guess I'd be somewhere in the same ballpark.

The TRUCKS! 2006 FX4 had 22" wheels and 33" tires with everything else stock and base lined at 202hp and in the low 200's for tq, i forget exactly what the number was...

I've got the the stock 18" wheels and 32" tires (285/65/18), AF1 3.25" intake, this exhaust setup, and an XCal2 tuned by Troyer Performance running on 93 octane fuel. I dyno'd at 246/301 but was running very rich at WOT. I haven't had a chance to mess with it much, or get it dyno'd again, I'll update when I do...

I did the exhaust first, and really didn't notice a change in power either way. When I added the intake and Xcal2 I noticed a HUGE difference. I was pleased with the truck after the exhaust mod, sounded much better than stock, but with the other performance mods I'm thrilled with how she drives!

 

I really love that sound. I had 40 series on my 2000 Dakota 4.7. Those videos make me want to go get a new exhaust system for my Ford

 

I have the same setup in my 01 King Ranch except for the x pipe. Does the x pipe make a difference? Might be the reason why i don't have equal sound on both sides. Any advice?

 

I remember that episode from last weekend, On that trucks episode, I cant believe the super low stock h/p and torque numbers from that truck.... they are rated 300h/p & 350 lbs of torque, whats it doing so underpowered, think the dude doesn't know how to really do a dyno or something?

 

ws6_guyscrew: I'm going to say that the low hp/tq numbers were partly due to the bigger wheels and tires they had on there. The HP seemed pretty reasonable to me, but the Tq #s seemed really low. If you read around Mike T. has some data on bone stock 04+ F150's and low 200's HP is not all that uncommon.

Galaxie4me: An X-pipe should only run you ~$50 installed... put one in and see if it helps. What exactly do you mean by it doesn't sound equal on both sides?

 

Looks good

 

what purpose does the x of the piping do?

 

Helps to equalize pressure between the two pipes and assists with scavenging.

Looks great! Nice work.
