In a post in the Fresh Alloy Z section, a sedan owner asked if the headers would fit a sedan. http://forums.freshalloy.com/ubbthre...b=5&o=&fpart=1

see link.

For you guys, I will have a set of these late this month and fit them up to my sedan. I will not have before and after dyno's unless someone wants to cough up 50.00 for a dyno session, but I will have before and after 1/4 mile times. I will most likely dyno after I put them on and having run the 1/4 a few times, I can extrapolate to within a few hp what the gains are.

the z link above mentions that there will be a group buy for these. These look good for expanding the power band on the Z, I hope the same is true with my sedan

I like em cause they are stainless steel and remove the cats, so will save some lot amount of weight.

Read the thread on these headers going on at my350z.com.

It's long, but raised question's in my mind.

Ivry 6mt sed
Crawford Pleneum
Injen CAI
22" resonator
Cusco sway bars
350Z springs&struts
Enkei RPM2

 

I will probably still go thru with it, as I have no problem going down there the next day after they fail to live up to a promise (naturally right after I cancel the payment on the credit card)

Also, as far as the hp claims and dispute on the board there, you will need a SAFC system to maximize the gains from headers. The headers on a VQ with 370 cc injectors will reach 80% duty cycle (theoretical maximum) at ~290 crank hp. After that you run the risk of running extremely lean (like 15 or 16 to 1 ratio)

Options are SAFC, Greddy E manage, larger injectors, larger fuel pump, FPR or a combination of the above.
