Loose pipe on one side.... how long do silicone couplers last?

[BrokeVW]

I was washing the Banshee today and noticed one pipe seems loose.

 

There is movement in the coupler between the silencer and the pipe, there appears to be a green silicone coupler there joining them, then a clamp over that.

 

The clamp is fully tight, closed up with no more squish left.

Do the silicone couplers crush over time and require replacement after so long?

 

The pipes are Pro Circuit Platinum and Pro Circuit 296 silencers.

 

There is also a bracket for the pipe front section to the frame, it is a rubber insulator and there is some cracking in the rubber and some movement, however the brackets on both sides seem to be equally cracked and flexible, but only the right side has movement in the pipe/silencer parts, at the coupler.

 

Everything is tight, I just can't get the one pipe solid feeling like the other and suspect it may need a new silicone coupler and new rubber insulated hanger.

I would call Jeff at FAST and order some new silicone couplers and brackets. I wouldn't screw around with the old brackets and couplers.

They aren't stock couplers and brackets, the stock Yamaha couplers and clamps came with the bike along with other stock parts, but installed on there now are these (the coupler is a thick green silicone version that you can't see in this pic):

 

I found these couplers at FAST, they fit most pipes but don't specifically say Pro Circuit in their list... I'll give them a call and make sure they fit my PC exhaust but I don't think I'll get new clamps, and I think I'm going to get stock Yamaha rubber brackets and o-rings for the front.

Thanks for the info on where to pick them up at!

Get a new hanger or drill threw the rubber and put a bolt in it. coupler shouldnt be used as a solution to get it to stop moving pipes should be pretty secure with just the springs and hanger with out the mid pipe and silencers even on.

I plan to get new hangers, new silicone couplers, and depending on the condition of the o-rings at the engine, new o-rings.

 

I guess I could swap the hangers from one side to the other to see if the hanger is at fault or if it is something else on that side allowing the movement.

There are only a couple places for movement to even occur if I'm looking at everything correctly... the o-rings and springs at the engine, the rubber Yamaha hanger at the front, the silicone coupler, and the rubber-washer insulated rear bolt for the silencer.

 

It is just 2 pieces to the exhaust from what I see, no middle pipe. The big ram-horn front section, the coupler, then the silencer.

Those Billit clamps that join the head pipe and stinger are available at cascade. Pretty sure they make them for different pipe combos. But they cost a bit.

In case you aren't familiar with Cascade Innovations- they are a shop here in Oregon. Replacement silicone couplers are available on their website.

I was not aware, but I just looked at their site and saw they list for all the brands except Pro Circuit, just like the FAST site but I'm sure they won't be too hard to find.

I am glad they mention on the site that they should be replaced once a year... that answers my original question!

I would bet a Golf Rallye one of the sizes would fit the PC's perfectly!

 

Give them a call; they would PROBABLY know.
