Good day,
I'm looking for some info on,
"Does a 6" DB killer restrict enough air to act as a Cat? If the ECU has certain variances of adjusting fuel/air depending on altitude, temp etc.
Would it not restrict enough airflow to not need a Flash or PC V?
I'm plan to run a OEM chopped header with M4 Slip on, stock filter.
My reasoning is I once had a GPR Homologated Slip-on with front and rear DB killer. They stated it did not need a different fuel map if both were used
If someone has some info on this I would greatly appreciate.
I am no superstar mechanic and limited knowledge on this stuff.
Don't beat me up if this has already been discussed but perhaps lead to me the stream!!!
Cheers
