straight Pipe= Lower EGT'S???

[fodpwr]

Hey guy's wondering if I straight piped my truck if it would lower the EGT'S? I have a cat delete and a banks monster exhaust on it now. Also I have herd if you run straight pipe you lose fuel mileage?

I just deleted the cat on my truck and now it runs about 100* cooler when i'm drivin up the mountain to work. I haven't deleted the muffler yet so when i get that done we'll see if it goes down anymore.

Getting rid of the cat alone lowers your egt. I have the 5" MBRP S.P. and mine are on average 200*-250* cooler than stock.

Like the guys above said.... I noticed a small drop when I removed the cat. I didn't see an real differences when I removed my muffler.

3.5" down tube, 4" straight pipe: cruise EGTs, about the same, standing on the right pedal, down about 200*. I have noticed that EGTs fall off quicker with the EGR cooler deleted. (I have an 03, I left the EGR valve inplace, it wasn't the problem). This quicker fall off is across the RPM range. In short, dumping that EGR cooler was the best bang for the buck in reducing EGTs.

I think when people say you get a drop in MPG they mean that you cant stay out of the skinny pedal after straight piping cuz it sounds SOO good... thus lower MPG

Dude, should've bought a cat back the first time. I did the same thing, 3 exhausts (cat back, resonantor delete, 3.5 down tube), 3 front lifts (add a leaf, add a leaf and hangers Pro-Comp Springs) and 2 rear lifts (blocks, then Pro-Comp springs)
