Default Re: Megan Racing Headers

Megan shipped me a new short header due to the fitment issues with cylinder 5 & 6. Will try test fitting again in a few weeks.

I received the (2nd batch) that had issues with cylinder 6 not matching up to the studs.
Called Megan and they sent me a new set of headers in 1 week. Since then the headers have been installed using OEM gaskets and so far pretty damn good set of headers for the price and service megan offers.

Installed mine the other day (with the modified short pipe) and they slipped right on and have great fitment everywhere (in an E36). First start this weekend as I am finishing up some other things at the same time. I also used OEM gaskets, fingers crossed for no leaks.

Mine have been fine for couple months now. Sound identical to my buddy with AA headers. Best Dollar to Value Mod.

Got mine in the mail today, measured it with a micrometer and they are equal distanct apart, maybe a couple mm off.

Default Re: Megan Racing Headers

I got my exhaust leak fixed and all is good. The car is loud but not too loud unless I floor it.

I don't like the rasp at ~2.5k and ~4k RPM though and the smell sucks too in the summer with the windows down, so I will be getting some 200 cell cats welded in.

Kind of a funny statement since a micrometer is solely used to tell how many mm. So was it equal or not

These are euro header reps (AA?Megan will claim CSL reps, but the material is thicker than CSL, probably thicker than euro and since thickness is the difference between CSL and euros [before 2005], so I would call these euro reps) which means they're raspy.

Get supersprint or supersprint reps like AP, SGT, Fabspeed, if you want to get rid of the midrange rasp from the headers. Or you could start throwing resonators in, downstream.

Cats also help with the rasp reduction.

Who here has run these headers longer than a year? I'm curious to see how long they last before cracking/failing, or if they do at all.
