Exclamation Megan Headers question??

Hey guys, i have a set of Megan headers but main questions are:

Does or Has anyone ever installed the Megan Headers into 350z/g35 2 or 4 doors?

If so, are the a simple straight bolt on or did you have to make modifications to it??

I had a customer come in here that bought a steering column pivot arm link, who he claimed that he had a problem installing the Megan headers in his 06 Z. He said when he Turned left to right the Pivot arm hit the header on the driver side.


Anyone know if this is true or not from previous experience..??

i can't comment specifically on the megans, but in 06 the steering rack design was changed and it is very common place to have header fitment issues because of that. like your cust stated, it is the slip joint that connects the shaft to the rack that rubs on the header.

you can try to move the slip joint up or down and that may gain you the clearance needed. if that does not work try grinding on the joint or changing the orientation of it.

my stillens rubbed badly under hard turns while accelerating--mainly at the track. it would rub so badly the steering wheel would lock until i let off the throttle.

Yea, he said he had 2 grind off a piece of the bolt but i was thinking the shop who did his work had slipped off the joint and when they installed it wasn't pushed down all the way.. He mentioned they DID have to slip it off..

but thanks for the quick response.. I'm trying to put a set of Megan's on an 06 g35 4dr a/t!

Mark the steering linkage. Remove the knuckle. Install headers. Install knuckle And align marks. Members have been doing this for 8 years.

I jet hotted mine and they went in no problem (with the steering knuckle) big pita as Nissan had attached the OEMs with a gun when they replaced my original oil consumer.

I didn't, the engine was replaced by Nissan and when they installed it they installed teh oem exhaust manifolds with the gun so the bolts were freaking tight.

This is the only video I have of the car. This is with a "silencer"

That was the first run, with the silencer. I removed it and the car got louder and just removing the silencer gave 30hp.

Middle of the runs while he was tuning the cams.

I thought I had a second battery, the one I had died after that.

271/264 was the max. Stroker is in the works.

so does this mean i might have fitment issues on my 06 g35 coupe? or were the steering components different in the g?
