Im thinking about getting stillin heards but im courious if it will increase the sound of the car.
also i was thinking about getting the greddy evo 2 and if i put the headers on will it make the sound of the exhust louder?

 

headers will give the stock exhaust a little rumble.........headers will affect any exhaust you put them on......in a good way

 

headers are great to get..... if you want a sound change... go HFC or exhaust...

 

ALright
Aslo i want to put just the rear kenstyle bumper on my black g35, Do you guys think its going to look good?

 

My borla give a nice rumble to my idle... i put exhaust and headers on at once so i dunno about the actual note
