i got these headers along with the hpipe and a flowmaster after cat exhaust. really woke my v6 up.it sounds like a small v8 at idle and roars when you open it up. my car is heavly modified and it dynoed a good 25hp increase with the rest of my mods.i would really recomend these headers if you want the best sounding exhaust for your v6. they are a lil difficult to install but with time and beer they go in there. 5 stars all the way.
