Damn You!!! Your depressing the hell out of me. I'm trying to make a torque monster and I was really looking forward to those LTs. You better find the fix and then tell everyone how you can pull a tree out roots and all. Anyways on to trying to find the problem. I wonder if the O2 sensor is getting a good reading? Where did the exhaust guy put them? Is there anyone else with LTs that can chime in?
Silver-
The LT's are 3"
The T-pipe is 3"
and I beleive that he has 2.5" duals out

I highly recommend the gibson shorties.
my old 5.9 QC 4x4 setup:
52mm fastman
modded kegger
K&N fipk w/6x9 round filter
r/t heads
gibson shorties
crower 1.7's
dual out flowmaster (2.25" outs).
MSD wires
MSD coil
mopar cap & rotor
autolite 3923's
insulated fuel lines
fuel cooler.
this setup made an awesome combo for everyday driving. easily accelerated in the mountains w/o downshifting and was able to get upper 14's for mileage if I kept my foot out of it. (actually got close to 16's on a road trip for 2 tanks of fuel)
Neon, if you want low end torque back, wrap your fuel lines, this wont give you a ton of power but it'll help.
edit: forgot to mention... 4.11's and 295-75-16 tires (34")

For the type of work that you do 20dodgeneon. You should look into the 1.7 rockers. That'll bring back low end too.

The way I understood it Long Tubes were supposed to increase the low end. I've also seen that eveyone generally agrees that 3" in the sweet spot in exhaust size. So why do you say he opened it up to much?

I’m calling BS. You guys have been around a long time and I respect your opinions but, to many people have said 3” was the perfect size. I’ve also been told by several people that 2.25” was the right size for true duals because they add up to 3”. Those LT should have added low end. There is something else causing the loss that maybe the new headers have exasperated. I think is cat is the problem. IT’s slowing down the exhaust because it’s basically a 5” pipe. I think if he puts a pipe in place of the cat most of his power will come back. Not to mention his plenum is probably screwed since he can’t run low grade gas without pinging.

think of it this way... you have a straw (or exhaust) that has a large oversized area in the middle of it (bubble) (same size on either end of the "bubble") when you blow thru the straw (flow thru the exhaust), you will have to fill up the bubble before getting the air to flow out of the other end. this is going to slow the flow down thru the straw (exhaust)
hope that makes sense, it was the best way I could think to try to explain it. I have a buddy with a chevy who put in a larger mid section between the cat & the muffler and had the same thing happen to him... lost low end torque.

with the right mods it will. the right mods will move more air than his old stock setup did. once those mods are in place the setup he has will start to shine.
