Full header back, drone at 1500 rpm on automatic

UEL uncatted header
overpipe frontpipe with cat and resonator
catback with Magnaflow resonators

I used to have a smile every time I drove my car, but now all I have is headaches!

Honestly I don't understand it, I don't mean to rag on just you. Why do people buy full systems like this without proper research when everywhere it's easily accessible to figure out they will drone.


1) The catback section will create the most sound difference with minimal horsepower so start there, either go to the stock catback or invest in something like a HKS Legamax or invidia Q300
2) Why 3 inch? That's totally unnecessary for an NA application is it not?

I have almost the same exhadt setup except that it is 2.5 inch and was thinking of getting a borla catback as it have a large muffler.
