Header output height different - this ok?

[dr-sicel]

So both L & R headers are installed on the gen 4 Coyote in the Mk5 - I noticed the passenger side header o/p is about 1.75” higher then the drivers side. The best I can determine, the engine is about 0.7 leaning towards the driver side. Not much, to be sure. I checked the mounts and it is sitting fully in the mounts… meaning seated to the bottom of both sides. Will this cause a problem installing the exhaust? the only real option is to raise the engine slightly on the driver side to even out the height, but not having worked with these at all I’m not sure what the norm is.

Thanks in advance

try to get the engine as level as possible. you'll find the difference between headers will be much better. I'd loosen the mounts and hoist it up and try shifting it a bit to see if you can get it level.

Excellent - thank you - much appreciated it!

I'm not to that point on my build yet, but see there are spacers FFR provides for the Coyote engine mounts. Are you using them?

You don't even have the adjustable intermediate section of the pipes on yet so what you are currently measuring is not meaningful. Until you install that and the sidepipes you really won't know what you have. Once you do that you can make adjustments as necessary.

In doing so, it seems that when I get it ‘evened out’, there’s a space on one side, as if I need a thicker spacer (I have them on both sides as per instructions). Is there a trick I’m missing?

Thanks Jeff - just saw this - I wondered if that would solve this, the intermediate section does provide a dimension of adjustment, when I get to that I suppose I’d have a bit of trade off between height and angle. So I’m hearing, don’t worry about it? …which would solve the space that’s created when I hoist up one side.

[dr-sicel]

Well, I got it down to an inch - improvement but not sure I can adjust more w/o something more aggressive - but based on the comments it’s, as the Brits say, “near as dammit”

The fast responses are super appreciate, when standing here trying to work it out, it’s nice to have the quick f/b!

Well you don't have the body on & you don't have the side pipes on, so what you're measuring is irrelevant. The engine isn't dead center on the centerline of the frame, so the headers, and pipes are not mirror images with the same dimensions. At this point you are just "caching your tail", do that when it's necessary.. This isn't a Revelle model kit with part "a" goes to part "b", you will have to make it work on many things

I haven't worked w/ MkV or Coyote but I can say that on SBF and MkII through MkIV there has always been a bunch of finagling to get header heights more equal. It was not at all unusual to have shims on one side of the engine only. One thing to keep in mind as you continue your build is that one can only see one side pipe at a time. Obviously you don't want one pipe to be two inches higher than the other but an inch difference no one will ever notice. It's much more obvious if the pipe is not parallel to the ground or parallel to the side of the car.
