Everything in my car is stock if i get headers how much louder is it gonna make my car compared to stock because i dont want my car to be very loud cause its annoying and id actually prefer it to be as quiet as possible
 


I don't know from experience but if you keep your car and factory exhaust I don't think you'll notice it being much if any louder.
 
I kept stock exhaust when I did my headers. Aside from the resonator leak, it sounds the same. The actual sound may be a tad more audible but there's no night and day difference.
 
Ive got headers on stock exhaust with cat removed. Its not too much louder. Gives it a better tone.

Yeah i plan on keeping the stock exhaust so in that case you guys are saying it shouldn't make much of a difference noise wise
 
It's not bad as long as you keep a cat. Even a high flow cat takes care of a lot of the noise. Overall though..it's not much louder.
 


You want a quality cat converter if you have emissions and or want to keep the o2 sensor from going off. A custom tune can help get rid of the codes forever.

Highflow cats are just that, high flow, they will flow too well for what the car normally see's for readings and will throw a cat code.

I mean you could hack your stock cat off and custom weld it back into the headers downpipe section if you wanted.
 
I have SD's no cat and stock catback. Its slightly louder but still sounds stock. This is all relative to how old your resonator and mufflers are also.
