Golf R down pipe ceramic coat or not

Guys

Have just taken delivery of my down pipe and want to get your experienced thoughts on weather it is worth ceramic coating it before installation.

Cheers

Golf R down pipe ceramic coat or not

I used to have a ceramic coated downpipe on my R - personally i wouldnt spend the money again. Never noticed any difference in heat/performance, and despite costing approx $250 for the coating, it started to chip/peel off in spots within about 6-8months of street use.

Ive now got a different down pipe and i just left this one raw stainless steel.

The only reason you'd do it is if you're worried about melting everything within the vicinity of the downpipe.

If it were me, I'd fit it as is, and maybe keep an eye on things.

Thanks guys for the feedback

Out of interest - which down pipe did you choose?

[prh1973]

Went with 42DD

Lucas_R do you know if I will need a o2 sensor spacer to avoid a cel fault?

Most likely - unless you have the tune modified to take this into account.

The 42DD is made of mild steel. I would get it coated just to stop it rusting away on you. Unless you want to change your dump pipes as ofter as lucas does[emoji6]

Otherwise it doesnt make a big difference. If you have a tune you wont need to worry about the o2 sensor.

It wont rust away. It will just look ugly.

Actually a few tunes still don't remove the cat efficiency check so you would need a spacer for that BUT I've seen some cars do very weird things when being fed an incorrect signal re trims and you don't have it as a failsafe anymore.

I've decided to stop coating our pipes now as we're using a heavy gauge material anyway and I just don't think people want to pay the extra on top anymore. If you use the not cheap Cerakote product its very good and yes the cheaper crap usually falls off pretty quickly.
Watch you shift cables with that one

[prh1973]

parso_rex can you tell me more about "watch out for your shift cables with this one" please?

[parso_rex]

just tie them out of the way as they will sit on the dump due to the radius of the single bend otherwise

Didn't know this! May have to have a closrr look at my installation.
