Test Pipes with no support brace, Normal?
Installed my 1320 Test pipes earlier. After removing my stock cats and installing the test pipes I noticed that there are no mounting brackets on them for the support brace. I figured that's how It was intended. There is a flex section on the test pipe and Y.
Since i installed my Y pipes and exhause a couple years back, I noticed there was vibration in comparison to the stock(obviously). But now, although it sounds better, the vibration has violently increased to a damn near rumble while accelerating and decelerating between 2 and 3k. The rumble goes straight to my feet and seat.
Iv hit the forms, YouTube, Google and the net all ... And its pretty mixed. I'm hoping to get a Vet's wisdom on this.
Questions are:
"Will running my current set(no support brace) up damage my headers(or exhaust)?"
Or
"Is a support brace for these test pipes not necessary? (being why they did not come with mounting points)"
If not(I'm hoping) I will suck it up and accept the new norm.
If so, do I just weld mounting plates straight to the pipes?

Well I just came out of the muffler shop
They won't touch it because "they are test pipes" (blah blah blah)
But he is telling me that the "droning frequency has increased. so its a natural occurrence for additional vibration to be generated due to resonation"....
So what he indirectly saying is. "I will do a resonation delete?"

There's no mystery here at all. Natural harmonics, heat, vibration will break any unsupported pipe, especially being so close to the main source of vibration, the engine.
Think of the pipes as you would a tuning fork. Once in motion, it just wants to keep moving until you put your finger on it to stop it. Same with a pipe. Only difference is the pipe has an inherent weakness, usually a junction, bend, or weld point.
Do yourself a favor, get some support on it even if you have to use an exhaust hanger with rubber isolator attached to the chassis.
Does no good to have an exhaust pipe act like a vaulter's pole.

I THOUGHT I was buying RS*R.... but the joker here at the local partshop sold me SR*S. But truth be told I can't tell the difference sound wise. I did some research on them after the fact of course, and I heard a bunch of stuff about rust. But I have been running it for 4 years... no rust. I am in Cali tho. Maybe they're having problems in Utah and Arizona and places like that.

the flex pipe isn't loose at all. I just think the vibration was so jarring that the noise was unbearable.

Humph* if that's the case, that would explain why these don't come stock with brackets.... sigh. Guess I'm damned if I do or don't. Well if im damned either way at least I don't have to deal with the vision distorting vibration in the cab.
