exhaust putty / paste

[Jungle_Jim]

hi guys, hopeful i will get to fit my backbox tonight or tomorrow, i was just wondering if i need to get some exhaust putty. its only a backbox, i dont know if i need it or whether its only used on flanged parts like where the cat and centre section meet
any help would be great
cheers

It doesn't really matter, it should just go on straight away, maybe put a litle on the inside around joints but it's noy 100% necessary to do it.

ok cheers buddy :y:

i've got a bit of putty on the joins just to ensure theres a good seal in the system :)

go out and buy 'gun gum' ;) put it on the joints/clamps tighten them up then start your saxo up leave it on idle for aobut 5mins then let it cool down for a good hour or so the gum should be nice and furm but also flexible at the sametime :).

[Noddy]

thats the stuff i was trying to think of last night ^^^ :D

So gun gum is better than exhaust paste?? Links to halfrauds please.

Gun Gum is for repairing holes in exhausts. What you want is Holts Fire Gum - it's a couple of quid for a tube at Halfrauds. :)

Any particular way you need to put it on? Rub it on with your finger on just squeeze it on??
Is it best to put in on the both pipe the inner pipe and the outer pipe to help bond??

holts fire gum is good stuff :y:

You can use silcon mate as it tends to handle movement better

are you sure it can handle high temp though?

holts fire gum works just like gun gum tbh just a different colour lmao.

[mattchewone]

Just used holts fire gum and its shite tbh i have used it before and not really thought alot of it. Still got a blowing really annoying have tighted the clamp as much as i physically can.

[Reid]

Aye it handle heat no bother
Loads of people use it

[JEEMO]

Could always try something like this.

Exhaust Silicone (http://cgi.ebay.co.uk/EXHAUST-GASKET-SILICONE-SEALANT-FLEXIBLE-200-DEGREESC_W0QQitemZ120244819921QQihZ002QQcategoryZ2 8641QQrdZ1QQssPageNameZWD1VQQcmdZViewItemQQ_trksid Zp1638Q2em118Q2el1247)

silicone is best especially on flanges.
i used loctite silicone on mine,really good stuff.
if its just for the slideing part of the exhaust just used gum gum.
dont use it for flanges though as it will just blow out.
silicone for flanges.
