How is the in-cabin drone before and after headers?
The ark exhaust has drone in low RPM but if push the gas you will hear best music you can hear, after the PPE headers the drone i think the drone reduce i will upload video in-cabin soon
Got the ark as well and same intake. How do you like the ppe headers performance and sound?
about sound before PPE the ARK exhaust sound perfect but i really want more loud so i get PPE the sound has be loud and perfect as i want and down shift sound fantastic before up shift has quiet but now has really good sound
about performance the car respond improve 1st and 2 st gear will push you back also on higher gear you will feel the power
I was thinking of getting the header. Does the car feel stronger with PPE header? And have run 1/4 miles.
after headers the car respond is better soon i will run 1/4 mile and also the sound is louder and perfect , if you down shift you hear crackle stronger than before
What are you doing about the lean condition that you've created by adding the headers? You heard the backfire more now because the car is over richening the fuel mixture to compensate for the lean condition.
