I would guess that not a lot of people with the 392 have done this mod... Hence the lack of responses...

I'll be putting their complete system from long tubes all the way back installed in a few weeks. It's being fabricated now and then I'll have to install. I'm to cheap to do a dyno before and after though lol.

long tubes make a few horsepower difference and actually loose torque on an untuned 392. Shouldnt be any real surprise, it was the same way when the 6.1's first came out

so how much will they pick up horsepower and torque wise once tuning is available......or at least how much did they pick up on the 6.1's

stick with 1 3/4 headers. Help keep the Torque

I have the full ARH catted system on from 1 7/8" long tube headers back to the tips and feel the power's stronger at higher revs but definitely a lot of torque missing down low. I've thrown several lean bank codes and the CEL is on all of the time. I love the sound and high end power but, without a tune, there's a LOT of potential thrown away. I'm hoping a cure in the way of tuneability is not to far off.

Running bigdaddies garage mini cats? Thats all I am using, stack there silver washer with the rear-o2 washers and no leaks and no codes. If your stacking the angle ones with the mini's, ditch the angle.

Yeah, I have the bigdaddies garage mini cats on but I'll have to check the O2 sensors and washer positions. I didn't do the install and tried to explain that the order of the washers was important. I'll have to check them out myself because I do NOT want to live with codes being thrown.
