i baught some new headers and it should be in the mail and at my door in a few days. questions - will my car sound different? how much different? better sounding or worse?

 

Do you have an exhaust?
Do you have an intake?

It should sound better, but if you have stock air box and exhaust you prolly won't hear much of a difference.

 

i have a short ram intake and stock exhaust all the way to the tip

 

good question. Same deal here my header is in the mail, but i have a catback and cold air intake, will it sound louder with the new header??

 

slightly louder, but nowhere near the difference you noticed when you did the catback.

 

so it will sound slightly louder. what about my power gain? its a 4-2-1 header and the website said 12 hp im pretty sure thats not whp but can someone clarify that for me?

 

Count more on 5-10 hp gain.

 

I usually cut the HP gains in half and go by that. You really never know what the gains are or if you really even gain anything without dyno'ing before and after. You can instances all the time that Performance parts actually loose HP.

 

should we need a header? it would be no use when the TURBO comes in place. lmao guys

 

time to get a cat back exhust..NOW
