If you don't change the down pipe doesn't that make it the bottleneck in the system?
I'm getting the predator (I thought today but UPS screwed up) and might get an exhaust system. How much difference is there when you dont change the down pipe.

The back door is for those times that the stock tune has not been restored and the tuner gets a glitch and doesn't recognize the truck.

Go to diablosport.com and download the latest update for your predator and install it.
You dealer probably changed the flash on your truck to a flash that the Predator doesn't recognize.

put it back to stock before taking it to the dealership...They reflashed it with a new flash that the predator didn't recognize at first. I downloaded the new 'f' version for predator, and then went back to the truck and got my 100HP tune back!
All is well in King Ranch 6.0 PSD land again

I didn't measure it with a dyno or anything...
but the turbo back exhaust gave me about 25 to 30 hp according to my butt-o-meter....
I would guess the cat back would give 15 to 20 ?????
Best check with Motorhaven as they may have a better idea though...

That WOULD make a difference...
around the dfw area there are too many "opportunities" to smoke em since I got em with all the traffic and stop signs and red lights....
That along with my remote starter long idle times just got too costly for my pockets
(and I normally could care less about fuelage ) the fun is too much to avoid for me.. too little self control I guess !!!!

Oh, they are like 16 year olds, they know everything. Oops, that was another thread.
