tbh I dont see it causing too many issues but surely its there for a reason?

perhaps your better off getting a better second hand one for it and swapping them over. it is only a tenner after all.

would it be the headshield thats rattling at 4000 rpm with my straight-thro de-cat exhaust?

(It always makes a metallic rattling sound just as it goes up thro 4000-4500 rpm, sounds pretty rally stylee but does make me wonder...)

that might be the downpipe heatshield

Ah rite, easily removed? necessary?
I'd be interested to hear what it sounds like without it, but now ive got pretty loud ticking/rattling noise from the head (in sync with the rpm) after a bit of motorway ragging session Sad

shes been good to me so far though...
Im thinking (/hoping) that its just the tappets, getting stuck or something, otherwise its gonna b valve/cam related Evil or Very Mad

Actually another thought was that it was a bearing in an aux. component such as the alternator, but after a listen again today it does sounds like its from the head

probably a tappet.

removing the downpipe heatshield won't make it much louder if at all. My chammys one squeaks at 80

squeaks? haha cant imagine
I guess ill have 2 record a video to show u what i mean, it reminds me in a way of my friends Civic Type R when it hits v-tec (although obviously not QUITE so extreme), it just makes this weird fast rattle-hiss sound and goes loud as.
It could well b the heatshield shaking because of the resonance from the exhaust @ that rev range, (like the exhaust creates a certain bass frequency tone @ 4000rpm that makes it shake), it also happens when i'm really slowing taking it up and down through 4000-4500 rpm.
Ah well anyways

how can I tell if the clicking is an injector f**kin up? It hasnt really lost much performance since the ticking has come on, it has symptoms of both really

is this about the the "tin foil" heat shield on the torpedo or is there a heat shield bolted to the manifold/downpipe as well?

heat sheilds for the win!!

my 19 wont start after a run if i don't have the sheild on that protects the starter motor from the exhaust manifold's heat.

Remove the bottom bulkhead one and you won't have any brakes after a run either.
