I was thinking about getting The True Dual Straight pipe. I have a 2004 f150 5.4 liter if anyone has a sound video of true duals. with all cats still on then post it please. The true dual im getting is just a straight pipe going from the cats all the way out the back on both sides.

 

like there isn't a million videos on youtube.

This 05 has the 4 cat system like all 2004s do.

those werent what i was looking for ive already seen those. theres no X or Y or H pipe. Its just 2 straight pipes going from the cats all the way back to the tips on each side of the truck.

 

ur not gonna run an X or H pipe? good luck tryin to get up a hill

 

That red 05 clearly says in info it has an X pipe...

 

I think he wants a vid WITHOUT any crossover... Anyway, it'll sound about the same as those trucks but with more rumble/cackle to it.

Pft! About the same as rollin' on those big *** rims!

 

haha. thats what my 4.10 gears are for

 

Well he can run no crossover & still get around, but he will notice the loss and it will rasp horribly.

 

go for it! just run a H pipe. i have one, and i usta have true dual straights and i think she sounded beautifully

 

You could always add a crossover later if you don't like it. I had an H, then no crossover, then H back in a different spot, and now X.

 

In your personal experience of trying both H and X, which performed better in low end, mid end, and high end power? Were these on the same truck?

 

In my personal experience, straight pipes are mainly for high school kids thriving for attention. It will be loud and obnoxious, and eventually you will want some mufflers.

 

All on the same truck. I might have lost a little throttle response taking the H out and running no crossover. After putting it back in, the cats came out. It actually felt like throttle response was better after tuning for it. As far as X goes? No difference in power to me, just sound.

 

Nomore improved low end with the X compared to the H?

 

Maybe on a dyno, but not in the seat that I could tell.
