anyone on here done a true dual exhaust set up from the manifolds back.... or headers, if so, what did ya use, and how much did it cost

 

It'd be sweet with a some high flow cats and some Flowmaster or Magnaflows under there I can imagine!

 

my dad was tellin me that from like '97 trucks and up would actually use more gas and it is some on how the computers work. here is this example he told me lets just say that the left of the engine is supposed to be dumping a certain amount of gas in the engine but the right side is dumping less so the computer tells the engine to dump more gas into the right side and i guess thats how it uses more gas, but i dont know if that is true so maybe someone can back me up on that one

 

if that were the case then u would be getting more power from the increased gas....... so that kinda makes it a give and take, so that wouldnt be all that bad. Also, i live in wisconsin, so i dont even need cats, i'd just need a couple mufflers

 

the computer doesn't sense the volume of "Gas" only the amount of oxygen. the computer uses the oxygen sensor to change the fuel to air ratio. 1 part to 14.7 parts is the what the computer trys to keep it at.

 

id like to see some honest straight pipes on a Ram- no cats, no mufflers- sounds like bigredram has teh chance to do that (in wisconsin)-- NC just passed a law that my truck wouldnt need cats either- but the exhaust system is just too pricey for me right now. hey man if you do it (without cats or mufflers) let me know how it sounds!!

 

thats ironic... the nation and the world is in a gas crisis along with a polution crisis and your state says its ok to have no cats...

i say to keep the cats...do everyone a favor ...

 

ok ill clarify- any vehicle 10 years or older (96) doesnt have to pass emissions inspections= no cats. so its not every vehicle just decade old ones

 

oh ok... either way it is still polite to keep a cat unless your draging on the weekends or a wicked street machine.. but a daily driver with no cat...

same here in ny... but thats only on clasic clasified vehicles... 20 yrs or older.. so a 86 or older vehicle doesnt ahve to have any cats on it

 

there has also been many studies showing that cats may actually hurt emissions with the reformulated gas than actually help it.
