I think the HSV headers will fit, I can’t easily see which component would foul the manifold?
It seems manifolds with Cyl 1 and maybe 3 tucked inside the engine mount, or 4-1 cluster near oil bypass port would have issue.
No reason HSV won’t clear?

Damn, thats disappointing. Got my HSV headers and mid section ready to fit soonish to our director, but really don't want to removed oem oil cooler as i wanted to keep it as stock (looking) as i could, hence why i bought the HSV stuff....

Long tube 4-1s like difillipo and hurricane sound the best in my opinion anyway.....

So why dont they fit them to the LSA's? Genie Tri-y's wont fit and the HSV's are even tighter to the motor.

Incorrect design spec for supercharged engine.
No, HSVs are no closer than stock, per same routing and cat entry.

Above is location of pokey HX, basically between engine and engine mount.

Above is looking through engine mount bracket to location of pokey HX.

Above is looking down cylinder 1 pipe, which runs outside the engine mount.

Basically part 7 moves part 9 about 5 cm further forward than oil filter location. The only header design that would foul part 9 are certain long tube 4-1 headers that run cylinder 1 on the inside bottom position.

If I get a chance, I'll put the Magnum up on ramps and have a look around underneath.
I have a pair of HSV headers and cats, I'll see if its possible to fit them.
I want to check the hangers on the mid section, to see if they're similar to a VE ute, as I have a 2.5" Maloo mid section I'm keen to try.

I hope you're right Monstar. I'm very keen to stick with the HSV headers. But, still planning on a tune anyway.

I wonder if any after market tri'y's will fit. I doubt it. Means long tube, which I'm not a fan of.
It's not that I don't like them Duanne. Just that for my car, application, I want to stick with tri-y and ideally HSV. I meant I should have said not in favour of fitting them to my MSE.
Some long tubes can have clearance issues too. I've never used 4-1's on an LS. Only on old school car by 8's. But I always thought they were better up top than bottom end torque?
