I recently got dc headers and removed the car and did a 2.5” down to the muffler which is a ktuned but the drone is just to loud inside could anyone recommend any resonators I’m trying to just get rid of the drone
there are several options. Ktuned, vibrant (get the hot dog/long one), invidia, Mugen... google is your friend
if you know how to fabricate or have a shop you trust you can have them add a dead end off shoot to add a bit of pressure. OEMs have been doing this forever.
you can also do a twin loop muffler setup that will kill a bit of it. Kseries engines just really dont sound all that great N/A
make sure the muffler tip is not echoing inside the bumper. ive seen too many people make that mistake it sounds awful
