I'm after some advice on the best way to fix a slightly leaky gasket in my TSL equal length header setup. Basically, I've been hearing a slight rasp on throttle lift when the car is warm. While fitting new CDF Racing droplinks today (made big difference over knackered old standard front droplinks) I thought I'd trace the "rasp".

My son was blipping the throttle and I could see a small whiff of steam/exhaust smoke coming from this joint gasket (green arrow below).



Now would it be better to;
(a) drop the headers
or
(b) drop the up-pipe to turbo
in order to replace this gasket?

I'm thinking (a) headers as they are easier to get at and the manifold gaskets are relatively cheap.

The other thing is that this system is not factory so I'm not sure what gasket I need for the blowing joint? It looks like a conventional O ring exhaust gasket so I'll probably pop the old one out and take it to a local motor factors to see if they can match it.

I can't find the manifold on TSL's website anymore so will call them tomorrow for advice as well.

Any advice/pointers welcome Thanks guys.

i would drop the headers to do this as the up pipe is alot of time i think the headers only 6 bolts i think

You won't need to remove either the manifold or uppipe as the the gasket can be replaced in situ. I would try pulling up on the original gasket first as geniune Subaru gaskets are very robust.

So there will be enough give in the pipes to pop in a replacement gasket? It won't be an original Subaru gasket as the headers (TSL Motorsport Equal Length) and exhaust pipework are all TSL Motorsport items.

What do you mean by "pulling up"? Just tighten it in situ?

Yeah tighten in situ, there is enough give but you can loosen the manifold if need be. But to avoid disturbing gaskets I would fit in situ with a helping pair of hands.

do in situ as said at worse case take the headers off rather than the up pipe
you can get the block to header gaskets from a motor factors to then
