Quick question about manifold-cat gasket and sealant

[ScarySquirrel]

Hi all,

My exhaust is blowing slightly (I think) and I want to fix it.

I recently resealed (and put a new clamp) on the cat-cat back join, and I also recently fitted a new gasket/bolts to the manifold-cat join. However I did not use sealant on the manifold-cat bit.

1. Should I have done?
2. Can I use sealant there?

Spanks.

no and no, did you use a genuine kit or a cheapo mickey mouse one?

Ok, that's good to know.

I bought it from NorthWest Performance - http://www.northwestperformance.co....ducts_id=20&osCsid=rkpihhbh6qkls8ag6r515on800

Is this a cheapo one? Will it make much difference if it is?

Every exhaust i've had on my 172/182 has leaked, i've given up lol.

Mine also leaks when cold, but once the ss exhaust heats up it will expand and unless you got major blows the leaks will stop.

use genuine kits

use genuine kits

+1 Follow the mans advice,

I fitted an NW one when i got my Milltek almost two years back now, It blew straight from the word go more so than the old one, Within a week of faffing with it at work i had gone to Renault and got a genuine one.

Couple of months back, after i had the cat back on i fitted a new one at the same time, Thinking NW might have changed their suplier, Nope did the same, So had a trip to Renault again.

I seem to recall Renault are £30 for them, but they work its fit and forget.


When i looked at the NW one compared to standard it didnt fit into the cat as far as the Renault one does therefore doesnt create as good a seal the shape seems to be off a bit too.
