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?

A catted front pipe will help. I don't think 100%, but it will make quite a difference. I do believe that a turbo will muffle some of that in the future as well.

A resonator will help a good amount. I just put one on mine that had the same issue after 3k rpm.

I ordered the cat for the header,
the only problem now, it makes a tracktor noise when i accelerate like a fluttering noise, sounds like something in the front.

flutter noise at low rpm is just how the engine sounds. I know the sound. The raspy can be easily fixed with just a resonator or put back the two with magnaflow ones. You in ontario?

It could be the engine, or an exhaust leak.

if you have an exhaust leak you should be able to see it by inspecting all the gasket locations with a flashlight, all around the ports / joints. You will see black soot. You have to really look for it, not just half ass it. I suspect the shops you had look at it may have just glanced at it or put it on the lift and ran it at idle.
Leak or hitting are most likely as others have said.

Catted/resonated front pipe will help a lot, and the cat in the header will also help. The resonator in the Magnaflow midpipe is rather short. A longer one like in the Perrin/OEM resonated catback will likely get rid of most if not all the rasp.
