Re: 3.7l performance love

Think this would have happened using wrap on the headers?

Re: 3.7l performance love

it would be faster in the quarter becuase of the 0-60 throttle restriction (system isnt really at WOT until u hit 60) and torque management both hurt my speed down low.

Open loop delays are pretty bad on the NGC trucks. in 3rd gear you have cat overtemp protection too.

If your looking at just a cat-back, ive ran diffrent systems. i had a dynomax ultraflow ss and it wasnt too bad, i have a custom flowmaster super 44 setup now and to me it sounds meaner...i also removed the cats and it helped the sound( hurt my low end some but mid to top end power feels stronger)

SCT can remove the CEL , removing the cats does not always result in a CEL.
