Exhaust back box or rear silencer

Hey chaps what is the going rate for a rear back box for a 944 turbo?

What is the best bet, Dansk?
 
OE back box is hugely expensive. I'd avoid Dansk having read many previous remarks on these back boxes and compared the quality to OE.

You'd perhaps be better considering a custom system. I plan to use Stainless Creations in Falkirk to upgrade the system on my 968 in 2014.
 
When mine went a few months back I looked at OE, Dansk and there was Longlife recommended on here to me.
I got mine a Longlife fitted and its been brilliant. I can't remember what the original price should have been but from the bottom of the manifold back (no cat) cost me £320 fully fitted but I got a misprice and a bit of discount. A back box only should be considerably cheaper.
They also come with a lifetime guarantee which includes labour (I've utilised this already as need the hanger modified), guarantee can also be passed on when/if you sell the car.
I really like the quality and the sound (there's 3 levels you can choose from) of it!
 
Longlife recommended on here to me
It was my recommendation - pleased to see it worked out OK - phew!
My Longlife system from the manifolds back (2.7 had the factory decat option) was £400 all in. It has no clamp or butt joints - just a few weld joints. I went for the loud option, so at the front end there are three short sections of sequentially wider pipe then a drainpipe all the way to a smallish can at the rear and a big round tailpipe. I haven't had any dyno checks done, but I am hitting the rev limiter a lot more than before so it must be running freely at higher revs I guess. Love growling around town too - it made the car feel totally different and a lot more fun.
 
These long life ones sound great.

I have always used Dansk for standard cars and Fabspeed for high performance options. Never had a problem with a Dansk, however I do buy direct from Dansk and every one I have head of there being a problem with, seems to have come from somewhere else, so not sure if Dansk make a cheap version.. Never had a dansk fail that we have fitted, and I have some customers who have had them on their cars for 10 years, one of which has done 100k miles!!

But, to be honest, if these long life ones are as good as they sound, and go all the way forward, they sound like good value.

I fitted a second hand, low mileage Dansk SS back box to my turbo ~ 5 yrs ago, never had any problems with it since.Only slight niggle I had was that the flange to centre section bolt holes were slightly out of alignment, easily solved with a file and drill !
 
The dansk back box I had was better built then the long life I had made up. But the dansk didn't fit over the rear roll bar and had a huge dent in it from the last owners roll bar.

Long life systems are a cheap system. Not ment to go rusty e.c.t but mine tarnished very quick, was told its due to the heat put out from engine. Long life system are just put together from per made bends. With push fit between main sections. They cut the flange off my down pipe and shelved over it. Wasn't a a bad sounding system and I ask for quite. But it drown on start up and pissed my nabours off. Could hear the car from a few roads away. Prob a bit rice really.

Fabspeed is just to much so I prob end up getting a system made up
For my turbo.

Shall keep an eye on my system for it tarnishing this winter as think if its going to do it it will do it then. Advantage though if it does and is damaging to the system they will be fixed under guarantee as its lifetime.
I guess another thing with the longlife ones is it comes down to the fitters and the individual jobs that each of them do :/
surprised at you having trouble with the sound. I've got the "mild" tone on mine and its got a lovely idle burble much like standard and sounds nice as you drive the car and go through the rev range, and when cruising isnt over powering at all.
Exhaust unfortunately I couldn't get an exact standard oval style OEM tip but got a basic not to large sing round pipe and doesn't look out of place.
 
I had a twin oval tail pipe and got it placed between the diffuser nicely. Mine was on 2.5 16v.

The garage that did mine stopped and so was the lifetime warranty which is for the owner and car not car. This was the policy 3/4 years ago when I had mine done

I havnt got a diffuser on mine unfortunately :( so think would have looked off with twins
Though it can be used at the nearest longlife dealer should you have a "legitimate" reason you can not get back to the original fitting garage and the guarantee can be passed onto the new owner of the exhaust/car (though there is a charge of like £30 for this i believe). I don't know if these are changes made in the guarantee since you had it done?
 
Not an issue that car is no longer with us. I went to get a price for the turbo but was told they had stop doing them.

These would be fine on n/a cars if tubing size is kept the same. I'm sure u can spec oval tip. Get a decat system for same price as a replacement back box. Was around £250 when I had mine done.

Sorry for the lengthy link. Working via my phone. Here's a link to that place in Falkirk.

I didn't rate the Dansk but looks like others have been happy.
 
I was tempted myself, but I made a point of not saving the link to avoid temptation... [:D] (Even though I do have a set of new covers for them)

Steve, did you get those seats? I didnt hear back from you.

Crikey Simon. I didn't hear from you so I assumed you didn't receive my email via the forum. I didn't buy them. Tried to get a bargain (though they were already ok priced) but I think they sold elsewhere. Had they been local then I would have snapped them up. Sorry I didn't get your reply.
 
Not to worry. I got the email, but I replied using the PM system as I can access that from anywhere. Sorry.
 
thanks for the help and feedback chaps will speak to the falkirk chaps and see what the reckon!
 
Had a Longlife system put on my old 924S from downpipe to rear and opted for a DTM style upswept tailpipe which was fitted directly to the rear box so no little tube with a big tailpipe. Looked and sounded fantastic and still going strong on the car even though I don't have it anymore, cost around £390 in 2006. When I spoke to them about doing the job it became obvious the quality is not so much in the material but the quality of the welder doing the job luckily the one who did mine was excellent even welded a flange on for the connection to the downpipe.
