Ok so yesterday I had the car on the lift installing my MGW shifter(freaking rocks BTW

) and to my surprise I find rust! ive only had the system less than a year and the car has never seen salt. also isn't it stainless? how is this even possible? just thought ide share.

flows are mild steel. enjoy your new brown exhaust.

vroomapunk · 02-20-2014, 07:16 PM

I think flowmaster is generally mild steel unless it says otherwise.

Doesnt appear to be welded but, even if the system was stainless, the weld can still rust because of the material used to weld/impurities in it.

If its painted black, its probably not stainless

HypnotiqSS · 02-20-2014, 07:18 PM

I have the catback so no welds
I didn't notice this on any of the other clamps but I don't remember. im doing an oil change tomorrow so ill re inspect

Mild steel exhaust is cheap but they rust. Stainless steel exhaust costs more but they last.

HypnotiqSS · 02-20-2014, 07:29 PM

will the 409 stainless just develop surface rust, or will it eventually eat all the way through? either way I think flowmaster has a lifetime warranty.

It looks like there's more rust on the trailing (I think) but there's always going to be salt and sand just elements it's a never ending fight.

Stainless will not rust through.....my manga flow has a little surface rust.

My flows out laws are rusted to but they sound awesome

Eddiefuzz · 02-21-2014, 03:58 AM

There is moisture in exhaust fumes, it's rusting faster on the inside. Cherry Bombs lasted me 18 months. Keep the warranty paperwork handy..BORLA BABY!!

HypnotiqSS · 02-21-2014, 06:24 AM

To be honest I didn't get them because of the price or quality, I just love the sound lol

SSGUNNER · 02-21-2014, 10:14 AM

Interesting. I will need go inspect my American Thunder. Flowmaster has lifetime warranty???

strych9 · 02-21-2014, 10:40 AM

No rust on mine. It isn't a daily driver, so not a fair comparison. Almost two years on mine.

Destructo09 · 02-21-2014, 11:16 AM

I think the exhaust tubing is stainless but the muffler certainly are not. I had flowmasters on my old truck for years, they got rusty but are built pretty beefy so it would take a long time for them to rust through.

I have a American thunder catback on my car, no clue how long it's been on there since it came on the car when I bought it, but it's not really that rusty.
