Ford, Chevy, Chrysler, Mack Truck, etc. Machine bent systems come off and assembly line where the bends are made by giant presses and require no sand in the pipe. The pressure of the machines was huge. The presses would have 3 or four stations with different dies to make different bends. Pipes went down the line and were handed from one worker to the other who placed the pipe in the die prior to the next downstroke of the press. These pipes typically had a bit of lateral rippling on the inside radius and since the pipes are unseen on a auto, that was fine. Some were stainless alloy (Chrysler) and some like Ford were pretty much just raw steel. The pipes were formed by taking sheets of metal and cutting them into strips and the strips were rolled up and machine welded. For some reason they called this process seamless tubing. Each run of parts had its own quality standard.
Hand bent pipes are taking a piece of raw tubing, made exactly the same way and putting it into a bending machine, filling with sand, heating and bending. The bending machine is typically just a curved die and an attachment at one end and some manpower to bend the tubing around the open die. This tubing will either develop lateral splits but mostly bends and tends to be a bit smoother on the inside radius. Sand is put in the tubing to keep it from cracking.
The most common defect with seamless tubing is for pin holes along the weld.
Wire,
An excellent and informative post. Thank you.

BTW the Honda Shadow series in 2014 had an MSRP starting at $7495, a 25% increase in price with virtually no changes.
To put it another way, my 1977 Kawasaki 1000 4 cylinder had a suggested list of $2295 ( I only paid $1888 out the door for mine) and that 83 hp bike was King of the streets at that time. What makes a 50 hp twin cylinder Honda V twin 750 worth 3 times that?
hmmm.. just a thought, but, what did a house cost in 1977 ?
I have a feeling that today's $7495 readjusted to a dollar in 1977, is probably a bit less than $1888, no ?

Well a calculator I just found on google says $7617.26 today would translate to $1888 in 1977. So a 750 Shadow today costs about the same as that KZ1000 did back then.
House depends on how big, how many bedrooms and where it's located. Are you talking a 2 bedroom house in Clermont Co Ohio where I live or a 4 bedroom house in Los Angeles, California?
Motorcycles have a MSRP thats constant either in Ohio or Ca so easy to compare.

OK, in that case I'm in error. And there's no way that a 750 Shadow can compare with the KZ1000 in terms of impact.. No one today would call the 750 Shadow 'The King' as the Z-1/1000 was then..
I guess I would complain then that bikes are so expensive today, but we're getting so much more capability now than we got then, that I'll happily take it, oil cooled spark plug seats and all :-)

So, Hedge... where is that review of the Ryujin exhaust?

I believe that I am the first person in the US to get this exhaust for the CB1100 and as part of my deal with Mr T I have to fully review it for him and send him pictures and video of before and after.
After careful analysis of all full exhaust systems that work with the CB1100 I felt that this one would meets all my needs:[ul] [li]Black Full Exhaust[/li] [li]No Cat[/li] [li]Baffle can be removed[/li] [li]Center stand can be used[/li] [li]Oil drain plug and filter can be accessed
[/li][/ul] http://ryujin-japan.jp/service/campaign/cb1100_1.html
Shout out to Mr T - Thanks for taking the time to fully answer all of my questions and making me feel 100% comfortable with doing business with you!
Note to Forum members - Mr T and I traded about 10 emails to put together this order. He showed great respect, patience and Business professionalism fully answering me in detail all of my questions and concerns. There are a bunch of other goodies that will arrive with the exhaust system that I will review for all of you and Mr T as well.
