I like that thought, does your cel stay on though, since it's not getting the 'Stock' readings from the o2 sensors and the egr setup?

 

I'm pretty sure he has an Xcal 2 that has the back set of 02 sensors shut off. Meaning he is only using the 2 in the header.

 

i put the simulators in when i did it and the light never came on.

 

Which is louder super 44 or 40? (inside and out). Also is it too loud, or is it something bearable? I'm thinking of gettting a super 44, and im not sure if i should go with the 50 instead since it is quieter inside?

Thanks

 

i havent heard the super 44, but the 40's are loud inside or out. if ur looking for something alittle more quiet in the cab than i would go with the magnaflows. it also depends where u decide to exit with the exhaust i have side exit in front of the rear tire and its loud as hell inside.

 

So a rear exit out the back would be probably the most quiet?

 

The farther the exit is from the cab, the quieter it will be in the cab. Straight out the back will be the quietest in the cab unless you tow - then I'd recommend side exit behind the rear wheels.
