I have a 1988 22re 4wd 5 speed, with an exhaust leak at the flange right below the exhaust manifold. The source of the leak is the nut closest to the driver side fender backed off and is gone. Everything I have read has said to replace the studs and gaskets, but I cannot find a reliable part number to order because I have read those exhaust gaskets have one size for the manifold and one for the catalytic converter. Also, the studs that have been suggested are doorman and they come in a 2 pack is this correct? Will I have to order 2 of these to replace all 3 studs and nuts on the flange?

Thank you for the help.

 

Give these numbers with your VIN to the dealer parts counter..
17410a, nut x3
17152, stud x3
17410b, forward gasket x2
17451, rear gasket x1

And it's an "intermediate/forward pipe". Downpipes are what connects a turbocharger to a forward pipe. Sorry just a pet peeve =P and I haven't had my coffee

 

Q&A,
Yes two pack, yes, and the first ones not really a question but yes it's two sizes you'll need three in total if your doing them all.

 

Thanks I know down pipe isn't the correct term had a brain fart while working on my coffee myself, I would have said y pipe but that is for V style engines so. How much does that cost from the stealership?

 

My NAPA has this hardware on hand but comes with brass nuts. Im getting ready to make a post about it.

 

Under 10$ for the hardware. Not sure about the gaskets

 

I was looking at the Toyota Parts Departments. Will the Doorman Studs and nuts work for this application?

 

Any proper sized m10-1.25 40L hardware will fit, but for 50¢ more I'd rather have OEM split or flared exhaust hardware over dorman brass straight nuts.

unless your dealership is Stevenson down in Denver, in which case you'll need to rising sun discount to get a decent price. I don't know why they over charge so much over everywhere else..
