Hi folks,

Does anyone have any pics of how the rear exhaust hanger is supposed to sit/fit?

It looks like I have a sports system fitted (as I do not have any right angle boxes and at a guess its a 1.5" straight thru), and the rear box is hitting the mounting which, sits lower than the hanging point.

They say a pic speaks 1000 words:



I have had to bend the mounting point away from the tail section (hence the bend to the left) but originally it was straight. It seems strange that the hanger that fixes to the body sits lower than the mounting point on the rear box?
You can see where its been hitting as its rubbed the pipe.

Any pics/advise?

Thanks

Andrew

Usually on the sports system that Rimmers and the like sell don't have a mounting bracket there. In fact you have to remove said bracket altogether else it fouls the back box.

As Mart says that OE hanger is for the original fit twin pipe system and should hang straight.
If you fit the twin box sports system you dont use this hanger at all...take it off.

Then it hangs at the back on a cotton reel and some abortion of a bracket that goes between a hole in the boot floor and the wing flange, in which a hole is drilled.

Or you do it properly, take the tank out and fit a proper mounting through the boot floor.

Or you drill a hole in the boot floor under the tank and fit a rivnut in there and screw the bobbin into it

The bracket on the OPs car is NOT the original, it looks like a home made aluminium copy.

I have done this with the sports system on the Carledo, cutting the bracket off the old tail pipe and welding it onto the sports box with everything jacked up and held in the correct spot and it works fine. But I have the original Sprint bracket on the body which has shorter tangs with turned up inner ends to stop the rubbers falling off. these miss the silencer by a good 1/2". Pic later when I've gone through the photobucket rigmarole.

That looks more like a non-stainless tail pipe not a Rimmers Sport rear silencer, I don't think that is a sport system at all but a mild steel one:

Thanks for the info guys

No idea if it's original..definitely not ally or homemade however.
System is mild steel, but why does it have to be SS if it's sports? It's straight thru apart from a single in line resonator, it's restriction free. Either way..mounting point on the pipe is original as welding is neat and bracket is properly formed.
Perhaps we get different systems and types over here? Remember we get no salt on our roads and so mild steel systems last for 20+years here. Personally I prefer the mild steel 'sound' anyway. The SS systems always sound too 'tingy' too me.

Anyway..I'll see what I can work out. I have new cotton reel mounts coming so I'll see how it sits when they have all been renewed.

The bracket I was referring to as home-made is the one between the body and the rubbers, not the one on the pipe! the original is a pressed steel thing that bolts to the body with 2 bolts aligned vertically. most standard ones would not be that thick, nor would they have taken that much bend without cracking.

I think you may have a couple of specialist exhaust makers in Oz that do not supply to the UK. Over here there is only really one firm left supplying "sports" systems for the Sprint and that is Rimmer Bros stainless effort. TBH it is not a particularly good fit and several users have complained about nasty sympathetic resonances. But it's what we have available, it's that or a bespoke system which would probably be at least twice as expensive.

I've taken a pic of mine, just gotta go through the photobucket procedure now!

Mine still has the rear bracket from when it had the Rimmer's sports exhaust.

Steve, did you know that the club now stocks the Sprint standard exhaust in stainless? It isn't cheap at £499 but I'm sure it will be better than anything else available.

My Sprint Auto has a stainless replica of a standard system which was on it when I got it. I have no idea of its ancestry but its quite old and still nice and shiny and seems to fit well. The car has not been taxed since 95 so I guess its at least that old. So I don't need one personally but it does make the car seem like a bargain for the £375 I paid!

I was referring to the dearth of decent "sports" or free flowing systems now available, there used to be at least half a dozen choices, now it's down to Rimmers, DIY, or possibly something from Jigsaw, but I think that might only be a seldom available big bore downpipe (which doesn't fit too well by all accounts)
In their defence, I have to admit i'm pretty pleased with the Rimmers Sports system on the Carledo. I knew before I ordered it, that I was going to have to modify it somewhat to fit my short tail car and also anticipated problems marrying it to the mild steel Vauxhall downpipe. In the end I cut about 1" off the rear of the cross axle pipe and another 1.5" off the front of the rear box and re-slit the pipe for the join. Then 4-5" slash cut off the tail pipe and it was all good. I made (or modified) all original type mounts in the standard places and the downpipe turned out to be no bother at all fitting neatly inside the Rimmers centre section. My only problem here was that the downpipe exits directly under the chassis leg rather than inside it and there was not enough clearance for a U bolt clamp, so a heavy duty Jubilee clip and a small tack weld keep it together. It's been on there 2 years now and doesn't knock anywhere or have any nasty resonances that I can hear ( I am pretty deaf and the car is quite naturally noisy inside (from lack of sound insulation and addition of polybushing, not because of exhaust noise). Up to 4k rpm its relatively quiet and refined for cruising, 4-5k and it turns to a harder bark which becomes a satisfying howl from 5k to the redline (and limiter) at 6800. Aside from a slight tendency for the back box to twist and drop with time, which no amount of clamp tightening seems to fix, I've had no bother with it at all and the noise Gestapo at Castle Coombe were very impressed with it.
