Quicksilver Question - Please help its driving me mad!

[v6had]

Hi all

Firstly this post isnt going to be a moan about how loud the Quicksilver exhaust is as most would imagine by the thread title, i love the sound and really dont want to change anything about it but unfortunately it looks like i might have to resort back to the original if i cant get this problem sorted out soon.

I have had the Quicksilver exhaust fitted for sometime now and during that time i have visted a number of different garages to try and get the exhaust aligned properly so that it is centred when coming through the rear bumper. On evey ocassion they have managed to get it pretty much dead center but once i have been for a drive and the exhaust has warmed up it seems to have a mind of its own and starts to move updwards in the holes towards the top of the bumper. It is now dangerously close to burning the top of the exit holes therefore i havent been able to drive it as much as i would like to. Especially with the weather that we seem to be having at the moment this is killing me!

Please can someone help me or advise how I can get the exhaust to stay fairly central? Has anyone else experienced a similar issue with the Quicksilver exhaust? If so how was it rectified? On the last visit to a garage i think they adjusted the rear collection box but that doesnt have seem to have helped. Is there anything else i can do?

Thanks in advance for any help guys, im now on the verge of ripping my hair out because of this exhaust.

Hi,

When I fitted mine for the second time on my Phase 2. i took the full rear bumper off - as it made fitting so much easier, fitted the exhaust then got my dad to stand on it so it pulled the exhaust down. Bought 2 new clamps and fastened them really tightly. That was a year ago and it was fine.

Is it the old clamps you are using or did you buy new ones? The clamps may not be fitting around it properly and if not they can cause the exhaust to slip.

Matt.

I found the same with both my QS and K-Tec, basically fitted with the bumper off and removed the brackets that hold the exhaust to the car via the rubbers. Then put a M12 nut between the body bracket and the hanger- moving the exhaust pipes towards the top of the holes in the bumper.

If yours is too high may be worth loosening them and moving down and retightening, then with all clamps loose I would wrap a long metal bar in towels and shove down the exhaust pipes and lever them into centre, then get a mate to do up every clamp tight.

This sounds stupid but works very well and DennisV6 and I have done 4 exhausts between us this way.

I had this problem for a while with my old QS. Initially it migrated north so to speak! :badgrin:

BUT its not a fault of the back box. Eventually i got it fitted correctly and all was well.

Some people never get any problems at all. I think its down to the slightly bespoke build of the Vee's. Each and every one is a little different. You notice as the pipes are larger with the QS, and hence clearance issues are much more noticeable. I have followed std cars where the std pipes are not dead centre.

Keep at it using the suggestions as above and it can be done. I played for ages with mine, but got there in the end. IMO don't try to bend anything to make it fit, as it will just move back over time. Try to get it to sit right without pressure. Then tighten it up and it should stay put!

Good luck.

Hi Guys

Thanks for all your help and suggestions, I think im going to try and get the bumper off on saturday and have a play around with the positioning. Is it hard to remove the rear bumper?

 

[Matt]

Not too hard - plenty of info on this site where the nuts are located. Bit awkward to get at the ones right at the back of it once you've removed the plastic covers near the wheels though.

 

[v6had]

Sounds like this might be a bit of a nightmare but i will give it a go if it means i cant take it for a spin in this nice sunny weather.

Anyone in the local area thats has done this before and could possibly lend a hand? ( South East)

 

[Milky]

I'm Guildford way (south east), didn't have a problem fitting mine but more than happy to lend a hand sorting yours out. I have two new clamps if you have used the old ones that may be bent

 

[v6had]

Seeing that it was a nice day I thought I would have a go at taking off the bumper and sorting out this issue with my exhaust. After finally getting the bumper removed I loosened off the 13m bolts that hold the exhaust hangers and tried to move the exhaust down slightly hoping that it would help, after holding the bumper back in place to ensure the placement was correct I then re tightened up the hanger bolts. When the rear bumper was back in place both pipes were fairly central. I thought I had finally cracked it. Went out for a good spin to get the exhaust nice and warm, to my horror the exhaust had once again moved up again and was dangerously close to burning the bumper.

I'm really starting to lose my rag with this exhaust now and I'm contemplating swapping it back to the standard which I really don't want to do if I can help it. Has anyone got any other suggests that I can try?

I can't believe how much pressure the exhaust is under and why it keeps moving upwards once its warm. I ensured that everything was done up tight before replacing the bumper. I did also try the other suggestion of applying pressure to the backbox and then tightening the hanger bolts but that didn't seem to work either.

Can anyone else help?

I known this does not really help with your problem but I was lead to belive that the new k tec back boxes had some sort of ajustment bolts on it so you can line them up and stop this happening ??? Anyone know if this is right as I am about to buy one but might not bother if you get so many problems ??

 

[v6had]

I have been doing some more research on the forum looking for more solutions and I came across a few where people have said that they have loosened off the clamps, applied pressure to the exhaust and then retightened them. By clamps do they mean the actual exhaust clamps as apposed to the hanger bolts? Do you think there would be much movement if I would to try this? I’m about out of any other ideas so might have to give it a try anyway

There is lots of movement in the pipes thenselves, loosen the actual pipe clamps and if needed the collector box clamp on the LHS and that will give you some play.
I honesylt found the best way was to loosen everything, whack a breaker bar down the pipes and then move into the correct position and tighten everything with it held in the right place. Its fiddley but works.

This may be an obvious comment but, aswell as the clamps themselves, and IIRC there is a telescopic section which allows the exhaust to be positioned ...

This, AFAIK, is the best means of making the alignment adjustments ...

Someone may be able to clarify further ...

I encountered that type of problem as well!

When the exhaust is warming up, it's dangerously close to bumper's holes.
We already suffered to make it look pretty good but it goes up and left when it's hot then when it's cooler it takes his position back. I guess if it was a bit lower and down it would be nearly ok during hot sessions.
We already moved the telescopic section to fit it to the car otherwise that was just impossible to succeed.

So it's not bad but it's not great...

 

[v6had]

Martin - Sorry if this sounds stupid but you lost me with a few of the abbreviations. IIRC? AFAIK?

maxcarpone - Have you managed to now get yours position correctly or does it still move once the exhaust gets warm?

AFAIK = As Far As I Know
IIRC = If I Remember Correctly (Maybe? I'm not sure)

Well, it still moves when it's warm but it's normal, you can't avoid that. Because it's hot, the metal is lying a bit and as silent-blocs hold the back box, it turns around them.

So the best thing is trying to make it a bit lower so when it's hot, it moves up but without touching the rear bumper. That's what I'd like to do because I guess mine has touched the rear bumper this weekend on the racetrack. So I just wanted to know if there is something else that could help me put it in a better position.

might be some excessive play in the engine mounts as well that might compounding the problem ?

I'm now a member of the Quicksilver gang and am experiencing exactly the same problems, have taken it to 2 seperate dealers and neither could line it up properly. Was at Drivers Performance Centre in Glasgow today, they deal with Quicksilvers and he told me most of them need modifying in order for them to fit properly, (so its not just vee's). Mine sits too far to the left, they are going to cut one of the pipes and lengthen it by welding a sleeve to it, hopefully that will sort it.

 

[v6had]

SIMDOG123 - I managed to get mine sorted in the end by undoing the clamps either side, getting someone to push down on the tailpipes until the back box was in place. Then doing the clamps back up. I couldnt get over how much play there was in the clamps. The exhaust hasnt moved since. Give it a try mate!

 

[DAZ 5738]

I have the ktec exhaust on mine and just had new clamps put on as the old ones had rusted, making the exhaust leek a little for mot. Original clamps were pretty poor to be honest, so they had fitted some beefy buggers and tightened up well. The exhaust sits perfectly and no movement,glad you have it sorted as it sounded like a bit of a wee pain.......
