ok, i made a post earlier saying that ever since i put on my 4-1 header, my echaust sounds really raspy... ive got a apexi n1, if i got a longer resonator, would that get rid of the raspy sound? if so, where can i get one?

 

It should cure some raspyness. Any muffler shop will carry it.

 

does anyone know what size my apexi n1 resonator is?

 

what is a resonator?

 

It's like a glasspack or a baffle that will quiet the exhaust down.

As Justin said, any muffler shop will carry them. Another one or a longer one than you currently have will quiet the exhaust down. The N1 silencer will also help.

 

i dont want to put the silencer on, will putting a longer resonator on hurt performance?

 

I run a 12" resonator, you make the decision.

 

I've got 2 1/4" pipe from the cat back, 6" later I've got a Thrush glass pack. I HIGHLY RECOMEND throwing one in your piping. It'll run you 50bux which is so worth it, my Magnaflow went from low-tone clackclackclack 10k times a minute to a deep smooth tone. not sure what your riding, I hear other Civics consistantly that payed as much as you did and still makes me go UGHH as they pass by.

Sooner or later i'm going to get a sound clip of my car from 3k-7.4k to let people hear it since there is always someone that starts claiming i'm lame and dillusional

 

does a larger resonator hurt performance? also, does anyone know how long my apexi n1 catback resonator is?

 

How about getting under your car and measuring it?
