Raspy header and weird noise
This is my current setup,
Fa20club 4-1 EL header
Agency power over/front pipe
Magnaflow catback
i'm catless
It's raspy after 3k RPM how could I make it less raspy? Should i change my over/front pipe to get a catted one?
Also,
I get this weird noise in the front that sounds like a tractor , flutter noise.
Nothing is leaking, i got it triple checked at my garage guy.
Could i maybe need a bigger gasket for the header?
Also would the raspy go away once I go turbo?
