I am thinking of purchasing J's header. I have a 70mm HFC and 70mm dual cat back. How much louder will it actually make the exhaust? I am about as loud as i would like my exhaust to be. I wouldnt mind a little more of a grunt from the engine but i dont want my exhaust to be any louder. What should i expect?

 

Also i was wondering if there are any fitment issues for ap2s or more specific MY08?

 

louder, maybe. noticeable by you yes, noticeable by other/passenger, no. depending on the exhaust, makes it a lil raspy.

 

Hmm somehow I remember a friend saying header quiets down a little.

 

i have a t1r. and no it does not, it adds a different sound on top of the exhaust. i mean you can hear the original sound of the exhaust and then the header.

 

ans2k does t1r header have raspy sound to it at a high rpm?

 

i just hear it in the low rpms, like between 2500-and 3000 sometimes at 3500, but fater that, my exhaust takes command.

 

it might change your exhaust tone a little bit. If you have a quiet exhaust, you will definetly hear the exhaust flow through the header now. i know i do.

 

Fits fine on a 07 and it didn't incease the "volume" of my exhaust and TP, but did slightly change the tone.

 

Cool this is exactly what i was hoping to hear. I dont mind the change in tone or hearing the header from the engine bay actually i would like to hear a little more out of the engine bay. I just didnt want it to make the exit any louder. I have a 70mm Asura HFC with 70mm T1R-EM dual and it is a deep bass and pretty loud. Sounds great dont get me wrong, just couldnt handle much more noise from the exit.
