Exhaust selection advice

What is the deal/reason for for the “old school springs everywhere “ on the Carpenter pipes?

The sections fit has more tolerance & is not welded; plus it makes for easier section removal/replacement for research & track.

According to Bob, if you weld them up, they will crack. He highly recommended you not weld them. I guess large diameter 304 stainless will flex more than mild steel when heated, thus the need for springs.

@sonny is more qualified than I in welding concerns, but I've known a few, very successful stainless fabricators, that have said anything can be welded if you watch your heat and take your time.

Maybe Carpenter is balancing the cost of the system to make them more accessible. Time, labor and material costs could increase the price a few hundred dollars

how about youre headers with all 3(2 on right side 1 on left)tors for 07 r3 stock for now planning on the ram air what size 2 inch headers maybe?what about performance or would that be a waste of time?
 
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.

I do build a header that is a direct replacement for the stock header.
This will allow your CAT, or CAT delete and the three TORs to slide straight on, but not 2" that will burn your leg.
Many Customers are happy with this combination.





Roadster, not three mufflers, but you get "the picture"

 
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.
