Rear manifold cat heat vent pipe

Recommended Posts

Inevitably perhaps, the paint is peeling off the black duct pipe which guides heat up to the roof vent from the rear manifold cat.

I could paint it I guess, but think it might just disintegrate if I remove it to paint.

Can anyone suggest somewhere I can buy a section of replacement pipe of the right diameter to replace this with?

From the link it says the black is good for 200 degreesC.   Would that be good enough?

I have a question about this pipe;

do you think that the air is going down to the cat during the ride or it work like a chimney when the car stops?

Chimney, to remove hot air.

I fitted one of the JJC ones a few months back. Seems to be doing the job fine but the only thing grinding my gears is that its colour now clashes with my engine cover, :rolleyes: .

Well I didn't fancy the orange pipes, so I took a 7mm socket (screwdriver would have done too) to the jubilee clip...IMG_3720.thumb.jpg.8fbf6c23d2f10da9bb6bb43d2130756d.jpg


and a 12mm socket to free the bolt holding the top of the pipe...IMG_3722.thumb.jpg.72d49580df291cee8b44ba7ef7366879.jpg


And I cleaned up the frayed plastic wrap on the pipe, and gave it three coats of matt black BBQ paint!

The camera flash didn't like the matt black, but I rather do. The paint coverage is much more even that this photo would have you believe, and it's a much darker black in real life. Maybe I should take another without the flash, oh well.
