Lt's provide better flow...more flow than those flowmasters can handle...i would seriously consider a straight thru muffler vs chambered, these hemis like to breathe

What headers are you running Chefred? You are in CA and I am under the impression that long tube headers are not smog legal because they relocate cats. Is this true? I really wanna do LT headers but if they aren't emissions legal I don't know if its worth the headache.
Long tubes will flow better but will take more work to make them fit your exhaust. They will require a relocation of your cats. Shorty headers won't flow as good but definitely flow better than your stock manifold. They are also much cheaper than longtubes and require less installation difficulties. As for the muffler, check out magnaflows mufflers. They are a straight thru design unlike the flowmaster. The magnaflows will flow alot nicer than your flowmaster.

I think he runs pacesetters and yes he still passes smog inspections with BV heads no cats and a cam

Yeah I just checked his mod list and they are pacesetters...just don't know if he removes them for smog testing like his BFI. If I'm gonna go through the hassles of installing headers I want to do long tubes. I'm sure they would pass the actual test but figured they would fail the visual inspection. You think your 6.6 will pass smog? I've been following your build and wanna say good job man! Your truck is sweet! :smileup:
So are the shortys worth the money? Or should I invest in a CAI? I've also heard of people saying there aftermarket headers leak after a while. If I got the headers what kind of sound an performance gain would I get out of a set of headers (short headers)

To me the sound was not so much louder but maybe a slightly deeper tone.
shorts/mids/lt's are all worth it over stock manifolds and the shorties are direct bolt on with no interference to the cats location (i assume anyway).
The major powerband increase for the shorties will prob be down low and mid rpms with better than stock results at the high rpm.

Idk i havent had my truck inspected in like 2 years and they dont do smog test were i live in texas its pretty much you pay for it and your lights, horns and brakes work your good. And thanks for the compliment it was a long and exspensive mod to say the least im just glad the truck is back on the road at this point since it was down for 7 months or so.
