Aftermarket Stainless Steel Down pipe temp.

[nickygn23]

Quick question Gentlemen. How hot does it get at the flange where the downpipe meets the turbo. I have a small leak at the bottom. I see exhaust soot on my passenger header. I was thinking High temp R.T.V. Between the Flange and the turbo.
Its an R.J.C Downpipe.

Wow , i figured somebody would have checked the temperature over the years. I guess I'm going to Harbor freight to buy an inferred thermometer. I'll check back.

Definitely pick up an inexpensive Harbor Freight laser temp pointer they are pretty accurate , i point one on the blocks and intakes and intercoolers/pipes sometimes, never pointed it on the dp though

It gets really really frekkin hot there,, Permatex Ultra Red is a good bet,,but, most will suggest something isn't flat,,i've never ran a gasket there.

I should be removing the downpipe this weekend. I'll take a look.

Thank you Warp. That will definitely be an option if the Permatex doesn't work as planned.

In my opinion, the remflex gasket is the better option. I have run one for years with no issues. I've tried them all, copper, red rtv etc.

While you're at it, stud your turbo where the dp connects. It'll help with future removal. Those bolts can get janky and difficult to remove, sometimes they want to break.

I was unaware there's a gasket for that,, i would go that route 100%.

I just looked at your picture. You're showing the header flange where it meets the head. Remflex there too, remflex for turbo to header 3-bolt and remflex for turbo outlet to dp. I realize there was no gasket in these spots from the factory but over time these areas can be problematic and the remflex gaskets are a decent and somewhat easy fix

I haven't tried to remove them as of yet. Wife has been keeping me busy painting the house. Always something.
That's great advise with the studs. I'll look around for them.
