APEX'i N1 Dual rusting out

[Dano]

has any1 had this problem? right where the piping goes into the canister, its got a whole rusting out on each one... and i know its from fuel, and not condensation. I'm running extremely rich and im not sure y yet. I haven't had the exhaust very long, does any1 know if Apex'i has a warrenty and if so, wat it is?

thanks guys,-Dan

eekers man. Thats not good to hear. I thought they used stainless steel stuff....

BTW what part of az are you moving to?

Damn... I've had mine on for two years through New England salty winters and living on the ocean. They haven't got a speck or rust on them. The canisters are SS and shouldn't rust ever... and the pipes are coated to prevent rust...

I'd call the company you bought it from to get info about a warranty. I don't think they offer one... but who knows.

[Anand]

yea, I've had mine for more than 2 years and no rust what so ever...

like it was mentioned.. call up the place you bought it OR e-mail Apex-i and see what they say about it...

[Dano]

yeah, the canisters are stainless steel for the most part... the back of the canisters and the pipes are coated mild steel. I got it from enjuku, so i guess ill email them.

Fuel is not an oxidizer, is it? Moisture is still likely to be the oxidizer. Running rich might be the root cause though. Your EGT is probably higher than normal. This higher temp (if over 500*C) might be forcing chromium out of the matrix...chromium is what makes steel stainless. Or perhaps you just got a bad material lot, or bad weld filler.

500 degrees celicius...?!

Your exhaust pipes aren't glowing red, are they:pface

[Dano]

lol, no they are not glowing red. I dunno, all i know is that it sucks, and its happened very quickly, a few weeks ago they were normal on the outside (i know that doesnt say much) but with the design of the pipes angled up, i can see how watever kind of moisture (gas/condensation, etc) is in there... its rusting right where all that moisture would pool. so i dunno, im patching it up for now so i dont get sick over the exhaust fumes at every stop light.

Steel does not glow at 500*C. Radiation crosses into the visible spectrum around 650*C. The exhaust pipe is like a long heat exchanger for the 800*+ exhaust gasses.

My apexi N1 has no rust... been through a blizzard, salt, you name it.... I think the piping is SS...

Rob, you rock.

:rockon

Dan, it may be the slag that's rusting - or has it gone all the way through?

Mild steel ends on the canisters? Non-stainless piping? I won't knock another company's product, but that's just lame.

I want to see this thing when you get to Phoenix.

Sucks to hear Dan, sorry man. Call up some biotches and tell them whats up y0!!!

This is Ben by the way.

pheonix area? don't get your car stolen... :rolleyes

[Dano]

thanks for the encouraging words w1ngzero.

yeah, i patched the wholes up today. REALLY ghetto but should work... exhaust putty injected in the holes, two stainless steel plates screwed over the putty with sheet metal screws, then more putty around the edges,
