Forge Turbo Muffler Delete Pipe (EA113 KO4 Engine)
« on: February 18, 2017, 05:33:06 pm »
Good afternoon all,

Has anyone any experience of the above part? I've not read of anyone on here having one fitted, so wonder if it is a pointless noisy upgrade? There's no mention of any performance increase other than 'improved response'.

Cheers,
Dave

Buy the chinese boost pipe kit from ebay for around £120. Comes with a silencer delete pipe, charge and throttle pipes. Much better value. The part on its own will make no real difference

Along with an S3/6R intercooler and a modified discharge pipe (standard end cut off and replaced with a 2.25" rolled end), the forge part is a good way to delete the final O ring connection.  On it's own, zero gain.

If you still have the standard intercooler and leaky O ring connections, you might be surprised how different the engine feels after doing that.

Out of curiosity, I tried one of those aftermarket KO4 'hi flow' discharge pipe with muffler delete kits and was so underwhelmed, I sold it on immediately.   The factory parts are very good.  You just need to shift the O rings and get all of the boost instead of some of it.

Just an update to this. I've fitted the Forge muffler delete and the modified discharge pipe. I now have zero bayonet connections and it drives all the better for it and no more oily patches on the under tray.  Definitely worth doing this  :smiley:

There is no extra noise from the forge muffler delete.  Maybe it only affects K03 turbos?

A bit off topic but should there be some kind of seal in behind the muffler on the turbo? I took mine off my new turbo and didn't see one

Yep, there is an O ring in the compressor housing to seal the muffler. Part no. WHT006482.  74.8 x 1.65mm O ring. 

They're on back order from Germany as I need a new one.  Mine's squished flat a bit.

Surprised yours is boosting OK without one!

Before you order one, I took the seal out of my TTE420 to use on my KO4 in the meantime and noticed it's a bigger seal than I said above.  85mm diameter.

But you can see there definitely is a seal there, in KO4s at least.  KO3s may be different?

Thanks pudding, I've not fitted my k04 yet but when I took the muffler out there definetly isn't a seal there, there is a cut out for the seal to sit in which is why I was wondering.

I'll go to Audi at some point and order one along with the diverter valve mounting flange and a few other random bits.

It's odd that my "brand new" second hand turbo is missing the seal  :thinking:

I can confirm the part number I quoted for the seal is for a K03 turbo!

RE your KO4 missing it's seal, well that is just weird, but I guess humans can forget things sometimes!

The turbo is technically second hand and had a broken n75 valve so I suspect foul play by the previous owner!

I'll need to get a seal ordered as my boost pipes have arrived in Glasgow from china eventually so will be delivered by Wednesday!

These ones mate 261675948859.

Think they took my offer at £120, only problem I have is that I ordered them on the 1/3/17 and that's me just getting them.

I don't think they even sent them the first time. Had to pay £24 customs on top of the £120 too but sill much cheaper than uk suppliers.

Richie-VRS did you find part number for K04 seal between turbo and muffler?

Sadly not as of yet. I spoke to Cardiff audi on eBay as I was buying bits from them anyway, they say it's not available separately however I'm not sure if they just couldn't find it as it seems odd that an o ring isn't available.

I've not been into my local Audi yet.

If someone have spare one can mesaure it and then you can get it in store with o-rings... If we get dimension will help a lot...
