Exhaust selection advice

[sleeves]

Tig, Full penetration would be ideal which would require a purge of argon even though it is a lap joint. If the individual doing the welding is eating a banana and takes a break to go swing from a tree you might have a problem. All sarcasm aside it would require a welder that knows his @hit.

Another reason they may be sprung is that (and again I'll take @sonny 's input too) SS work hardens easily due to the high nickel content I think, making it stress fracture more easily than normal steel. This is why when replacing all the fasteners on your bike with SS you be selective, some are better left.

In my youth @Paul Bryant and I had this very dicussion in the weekend I replaced some fasteners on my cars suspension with the incorrect bolts and they stress fractured and the front wheel (disc, hub and brake) fell off, lucky I wasn't going fast, sadly that was another girl who never called me back. Suspension bolts are high tensile I discovered.

Haha sleeves quite the discovery learning incident there!!

So then Sonny is now the Brute welder?!?!?
Better contact Carp for the side job?
Why not just use the same material as @Paul Bryant & CES???

Because Stainless lasts for ever and a day, where as mild steel only lasts forever.

You see Bull, there is a lot of Marketing and Sales speak hype out there.
Sure Stainless does last for ever (and a day) but it's the "expectation" that every one has that has been lead by the Marketing People.

For example, how many times have you seen the blurb about "Triple Chrome Plated" Ye haaa !
This must be a great product, it's Triple chrome plated.
Now lets look at the standard chrome plating process.
First we have Copper;
Then we have Nickel;
Then we have Chrome.
Gee wow, Triple Chrome Plating !

Welding the stainless as was mentioned early may be the reason that the Carpenter pipes are held together by springs.
I doubt it as the pipes are constructed from sections and welded together anyway.
It may be a cost cutting exercise.
But possibly it's a marketing ploy?
Because all the Race Systems (on the Track) are held together with springs, it must be good, it's a "Race" system.

Springs on the track are great because if there is a crash or a pipe needs/wants to be replaced, it can be done so quickly.

On the road, slip joints held together with springs will deteriate over time (miles) and cause leaks.
This is not a problem on a race machine as they probably wouldn't do 500 miles in a year.

Often Race Track Technology doesn't transfer onto the street as a reliable, long term investment.
If you only ride around town and don't do many miles, ..... no problem.

If I keep looking at pics of Paul built headers resolve about not doing anything more to my 09 Touring is going to fade away.
Darn but those are beautiful headers. A set in black would look great on my son's 07 Classic and in silver on my Touring.
No, wait...I've got to come to my senses.

Mike,
Have you priced jusy the headers from @Paul Bryant?
If we but two sets, do we save any $$$?

@Paul Bryant
Gratitude for your post & all the info.
Trevor, of CES told me pretty much the same thing. He does not use stainless.
I have never kept a bike or exhaust long enough for the steel to deteriorate.
Is your system is the same or smaller size than the CES?

Haha sleeves quite the discovery learning incident there!!

Tis amazing the copious amount of noodle we have on this forum!

Does not pay as well. Motorcycle exhaust systems compared to Military Aircraft? Agree 100% percent with Paul. Agree with your comment. Could the pipes be welded vice springs and not crack. Yes if done correctly. Key word here is purged.

Only advantage I see for stainless is the ability to clean and look sharp & possibly a tad weight saving.
Not really a biggie for me . . . ceramic steel is just fine.
I would like to know if the @Paul Bryant header end is the same diameter as the CES so it would fit my existing can?

2” OD on @Paul Bryant header outlet. But he’ll make you a reducer. He sent a 2 > 1.5 reducer, coated, with mine
