quieting my straight pipe to magnaflow

[florida_dirt]

on my eta.

school me please. i daily drive this car. it's honestly to the point where it's annoying at idle when I'm at stoplights and driving on the highway.

trying to decide on a resonator or a cat or both?

Do you have a single 2.5"+ pipe? For my 3", the only resonator I found helpful was the vibrant ultra-quiet which is essentially a small second muffler. That killed most of my drone but I still needed a bigger muffler to get the db level tolerable.

Center muffler after the cat helps a lot, bigger the muffler the quiter.
