Light bleed through diffuser

I did the GS350 diffuser & exhaust modification on my GS450h. Now I am facing an issue. Apparently the exhaust tips cannot touch the diffuser since they get to hot. This leaves an area open where a lot of light bleeds through and from behind the ugly tailpipes are visible. See picture below:

Has anyone managed to cover that up?

I think mine has some kind of mesh cover covering that area. I don't think mine is that visible and I keep forgetting to take pics of it..

Thanks, this is something I'll do anyway. Although I am not sure if this has the complete desired effect. But it's cheap enough to do.

I'll post the result anyway.

AHHH! I didn't know the GSh only had the single.. very nice upgrade indeed!

If you ever want to convert to the single projector headlights, let me know. I'll take one for the team and swap you.

I don't know if the GSh has single exhaust, but he didn't have any chrome tips before.

two exhausts, tips pointed downwards. However they are not symetrical.
