Markski, I would like to share some tricks and why V bands just don't matter if they warp.. But reading you post's tells me..... Exhaust flange on a lathe/cnc??? To true it after welding??

 

Im not going to argue with you... my point was that I was surprised that they used steel that rusted which was welded to the a very expensive cat... I would not do that...
There is a procedure when it comes to welding.. An order of what is welded when to prevent warping... and when welding thin SS V band flanges you actually take that into account...
Nor have I openly nor privately said which exhaust it is...
If you like mild steel , as Im sure some do, on their P Car exhausts God bless you...

 

Markski, "There is a procedure when it comes to welding.. An order of what is welded when to prevent warping... and when welding thin SS V band flanges you actually take that into account..." Wow.. You did not respond to my post about 309 or 308 and you think people who truly know about welding believe you do?

 

Tim,
I have no doubt you know more when it comes to welding then I... but I choose not to sell exhausts with mild steel flanges... that is my choice. If you want to talk "welding" you can with my fabricator/ welder. Im sure you and he speak same language... But taking cheap shots is not cool either...

 

Maybe it's just the picture/angle, but to me the flange doesn't look rusty at all. Maybe a little discolored due to heat, with maybe some superficial oxidation on it... but it certainly doesn't look structurally compromised.

To be fair, you sure dropped a helluva big "hint" when you elaborated on the catalytic converters used. I know of only one major 996TT exhaust manufacturer that uses them. Assuming I'm right, you may not have named names, but sure left a big breadcrumb on the path leading there... just my $0.02.

 

I think this is the point where we can all agree that there are certainly different ways to view an object, person, situation etc.

Additionally, its always nice to welcome new information.

Ultimately, each shall choose their own way...

reminds me of one of them


ol-skool house anthems.

 

I never said it was structurally compromised... its not... It will be fine for life of the car...

I know of a minimum 3 companies that use those cats... nor did I name the cats... Most Euro ones use them...
And even if I did whats your problem with that? did I slam a board sponsor or attempt to indirectly?
Ive been on this board for 7 years... and do not have any issues with anyone... I say what I believe.. I do not expect everyone to agree...

 

Since you'd like to keep it professional, I'll do the dirty work.

Looks like...
HJS are the cats...
Fabspeed is the exhaust...

 

Markski, I am sorry but you speak and write as if you are the welder/fabricator. It is your choice to resell anything you like, I use 304, 321 or even inconel. Mostly 304 though, I would used mild flanges if the supplier I choose to use sold them. Hell the amount of times I change my set up mild steel pipe would not even get pitted. I do not own a car shop or even wish too.

 

Markski,

I think you may've taken my post the wrong way (or, I took your thread purpose the wrong way).

Rereading posts 1-5, the whole point of this thread seemed to say (paraphrasing) "wow, we were surprised to find one of our competitors cuts corners and uses mild steel flanges on their expensive exhaust with expensive cats - we only use superior SS flanges." The intent seems to be to promote your product in contrast to, and at the expense of, a competing product. The only manufacturer that I know of that uses those cats (if they're indeed the ones I'm thinking of) is a 6SO sponsor - you know of at least 3, so you obviously know more than I do (by orders of magnitude, I'm sure ) on this subject.

However, as this thread progressed, we find out those pictured flanges being mild steel may or may not even be the case - since the only analysis shared was "is it magnetic? yes" and others have chimed in that some grades of SS are magnetic, while others still have chimed in to say even if they are mild steel, mild steel flanges might actually have certain advantages and be chosen for a reason, not just to cut corners. The water's been muddied a bit there, to put it mildly.

Now, you say "those flanges will be fine for the life of the car" - if that's true, then what was the point of even starting this thread? Because it seemed at first like a warning/public-service-announcement - now it's just confusing.

I think 911 Tuning makes great products, from all of the feedback and reviews I've read - so I'm not bashing your stuff, believe me. Just don't see what the intent was of this thread, if you're saying the flanges are fine...?

 

Hi everyone,
I'm a little new at this so go easy on me but i just wanted to add my two cents. Actually, this is my first post! I actually have Marskis exhaust on my car (love it by the way) and took it over to a Porsche racing team in the Chicago land area to have an oil sending unit checked out. They looked at his exhaust and said "its about time someone uses all stainless steel". They explained to me that they only use stainless steel exhausts and flanges on their racing equipment. Obviously everyone has their difference of opinion, but this is just what I heard from a very top Porsche shop race team. Enjoy!

 

Do you practice construction law? I have a case for you if you do..

 

I will bite... Porsche motorsports cars use inconel! So unless the team you speak of is racing vintage or converted street cars I am unsure of what you are referring to.

You joined this forum to post this today? Why did you not join the day you installed you exhaust and give Markski a plug?

 

I prefer my stick welder and whatever metal I can hack off a stock exhaust at my buddies shop.

 

My intent was that I was "surprised" as the thread stated... I was very easy and carefully chose words... not disclosing the manufacturer... nor will I...furthermore this exhaust company is NOT a 6speed sponsor... Im sure some are reselling them... IDK to tell you the truth. You seem to be the only one deducing the name of the exhaust company.. why? let it go.... I was a member for 5 years before I became a sponsor.. Im guessing it would be ok then on in your yes to make the post but since I make exhausts that precludes me from doing it? My intention was to show that I was surprised since my fabricator raised an eyebrow as well... and he is by far a beginner... I did not go on slam, put down , not say its inferior... only when a handful of you jumped on me I became defensive. But if your telling me that you would rather buy a $4k exhaust with mild steel welded to SS parts over all SS system then we we have a difference of opinion... and this would be a surprise to me... so what's your problem starting with me? Or do you just like to argue? Because if you and Tim get off on that I'm the wrong guy and please get off this thread ... both of you...
