2nd Hand Exhaust - Replace the gaskets?


Glenn1981

Recommended Posts

I just picked up a very nice 2nd hand Jap exhaust, for a very good price. Got it through a week or so ago and it is in very good condition, the guy reckoned it had only covered 2k, I had my doubts but on getting it, it does look like it has hardly been used.

 

Anyway, the gaskets whilst ok, are a little brown. I am just wondering if I should buy some new gaskets for it before I take it to be fitted on Saturday, or if the ones on it will be okay.

 

If I should get new ones, are they universal and where can I pick some up?

 

Cheers

 

I will post a vid of it when fitted, but a clue is that it will be quite loud ;)

I thought it would probably be worthwhile. I am getting it fitted at a friends garage, he only does MOTs and small jobs, so I doubt he will have gaskets in stock.

 

Can I just grab some at Halfrauds or somewhere?

 

Are they universal or are there any special ones I need for this particular exhaust?

Right, I have been PMing Alex today and as much help as the good man has been, we couldnt get to the bottom of what gaskets I have, so I have measured with pics here so that Alex and you guys can help.

 

Are these just OEM gaskets?

 

I need 3 of the smaller ones for the extra join in the Y-Pipe and the cans and I need 1 large one for the join of the Y to the Mid section.

Can you guys give me a definative answer on what these are.

 

Also I need them for Saturday 9am, which will be tight for Alex to get them to me from Scotland, what with Good Friday. So anyone know where I can get them in North London \ Herts or nearby?

Can I just go to a Nissan Dealer.

 

Thanks Guys and Thanks Alex for your help so far, I wish you lived up the road! :lol:

Rather then measure the gaskets, I have measured the pipes on the exhaust, as per Alex's instruction :blush:

 

Large Pipe join of Y to Mid Pipe looks like just over 70mm hole

Small pipe join for tail pipes and extra Y join, looks to be 60mm

And here is the Y to Cat joins, as you can see the gasket is good as new

I have been all around today, to Nissan and various Exhaust suppliers and wholesalers and I have come up with nothing!

 

One place said that I could use the old gaskets with some loctite 5920 copper based and that would do the rick, so I may give that a go.

2.5 from the Cats to the Y is standard gasket I believe and the Y to the mid looks like a standard 3"

does the Y to cat good gasket fit on any of the other joints?

 

I got an APS 2.5" true dual and the bloomin thing has 4 x 4 bolts square joints - no chance of getting these so will have to resort to High Temp copper RTV like this (recomended by exhaust specialist)
