Driving the car last night it got dramatically loud and I could feel something through the floorboard. Guess the exhaust wanted to match the rust on the wheel wells.

 

I never saw rust eat stainless steel like that. :eek3:

 

looks like the gen 2 resonator pipe. the third version of the resonator is much better built

 

this is distrubing.

 

 

Holy <expletive>!

Is it possible for a shop to save that somehow? (maybe weld in an equal-sized pipe/connector)

 

Have an exhaust shop cut the before the rust weld in a new section with a flange and you should be good.get a test pipe too so your new section will mate to it better and last longer/sound better

 

Damn it that is why I love the weather in Cali...can get a little cold but Damn for that to happen it will be a long, long time....Good Luck on the fix....

 

Mileage, age?

 

140k

I'm 35

 

Take a picture of the entire bpipe please! T304 nor T409 corrodes like that! That might be something you modded onto your Cattman exhaust.....I've had T409 on my Hardbody for almost 10 yrs and it barely has any surface corrosion yet!

 

A/S/L?

 

The stock cat and flanges ionized (or w/e the process is) the SS. It just turned it into regular steel, basically.

I'm pretty sure I got that right, but I am kinda senile LOL

 

 

Ya, we're old school, BTW SEmy2k2go .... I'm 30

I was being stupid again, it's obviously a 2k2.

 

That looks like aluminized pipe IMO .

 

That does not look good. I cringed when I saw that. Move to AZ, NM, CA.

 

Ya, he probably just welded the rust on there...

 

to az ....

My 95 is old as shyt and doesn't have a single hint of rust.

 

S.O.L.?????

 

I think you're trying to hard.

 

On closer inspection, you're right. You can see what looks like peeling of the galvanization. And the horizontal lines where it hasn't rusted yet also looks like aluminized.
If it was SS the rusting would gradually taper off and not have an abrupt line. I retract my earlier post

 

Wait I thought these exhausts were stainless steel? Brian please step in and clarify...

 

Anywhere out of the rust belt.

 

I can guarantee that Cattman exhaust piping is SS and that picture is Aluminized steel.....T409 will get surface corrosion but that obviously was rotted thru.....please post a picture of your entire Bpipe or catback......I guarantee that's a OEM Bpipe or a modded Cattman bpipe in which it's front flange section was replace with a aluminized steel section.....Even though I'm in Texas I've had mufflers on my 86.5 HB last about 2 yrs maximum back when I uesd Dynomax Super Turbo Mufflers, they rusted from the inside out.....So I'm sure this isn't a Cattman exhaust until the Original poster generates a full picture of his alledged Cattman Exhaust!!!!!!

 

After looking closer and racking my memory (I've given up on caring about this car for a while now) I remembered that I only installed the Cattman rear section so the rust was actually on the OEM b-pipe. I got the repair done today, but there is still a really loud exhaust noise (leak would be my guess) up by the engine. I REALLY HATE putting money into this car and if it weren't paid off and I was paying for a wedding right now, it would be gone in a heartbeat.

at CMax03 for his very strong opinions of this issue and his demand for me to provide proof. I now remember why I relinquished my Super-Mod position and abandoned this wretched site.



Thread title can be changed to "Minor issue with my exhaust"

 

Glad you got taken care...

...my bolt/nuts are all snapping off becuz of this damn Ohio seasonal ****...

 

Pretty quick to jump on Cattman, but once again, not a faulty Cattman product.

Ha...noob, don't worry, I've backed Cattman for more years than you've been on this site. Nice try, now go away.

 

yea, this should happen after years... nothing an exhaust shop shouldnt be able to easily fix...

 

It should not happen to a stainless exhaust.

 

Strong facts on metallurgy is correct and your pictures proved that the aluminized coating was present and fading.....

 

its metal bro.... getting wet and hot on different days for sooo many years can cause that... aint no metal in destructable... sure its bad but this doesnt affect the durability for the catman exhaust not one bit to me... not really a hige deal though... exhaust shop and that should do... im sure this is the OP's daily and iirc he has had this setup for more than 5 yrs... anything can happen man, its an aged setup

 

My T409 SS 2.25" Catback has been in service for nearly 10 yrs on my Hardbody pickup and it has a little surface rust that can be removed with steel wool or a wire brush.....that exhaust was ate up all the way thru........that's not quite the same!
GH17 your SS silverware @ your house rust like that too????? LOL...My T304,T409, Titanium, and silverware is practically indestructible!!!!!

 

Are you trying to go out your way to make a point to find a metal that is "practiclly" indestructable? This was in context to exhaust, if u wanna go that far out, well we can... you can bend or break the silverware and the metal become so week that when you even try to get ice cream the metal just ben, silverware destroyed but what's that got to do with a catback, I bet the rust started from the bolts and ate its way through...

 

@ wretched.

 

I know rite?

 

hahaha A/S/L


type 69 if you want to chat

 

F.A.Y.U.T.A HAHAHA
