Hi Jason
I have two thoughts... one the baffle inside has detached and is rattling around or two some wise alec has thrown a stone or such into the tailpipe. As it's a relatively new box I'd be inclined to remove it and shake it around a little to see if it is just something thrown in there, worth a try before spending money on a replacement?

hiya,,,,,
i mentioned a little while back that my chaps thought i had a small blow in the exhaust or a bracket loose?,,,,
fast forward to last week and whilst the car was on the ramp and up in the air,,,,they showed me that the all brackets were good and the exhaust was good apart from the back box which had something small bouncing around inside it????,,,,new dansk fitted shortly before i bought her and no damage to the exhaust whatsoever?,,,,,so the not very loud at all noise i hear is this item bouncing around my back box,,,,
so it looks like getting a new back box or live with it?,, a new back box it will be then,,,,
Any ideas? how this could have got in there bearing in mind theres no damage whatsoever when they then i were looking at the exhaust when underneath her,,,,,,
cheers jasonp

Not too drastic - I would go to a custom exhaust supplier and ask, they can generally tailor to your volume requirements too...
if it has a catalytic converter then delete it but hang onto it, the amount of metals in the old ones is significan. A local place is paying another member £400 for his old one that erm . . . fell off his car on a run!

If it's a stone or a piece of baffle that won't come out, you could split the box open remove / secure it and weld back up...
No need to worry about or spend money on a de-Cat pipe or entire system replacement unless you're looking to go this route, You may need a live re-map without the Cat? due to the loss of mid range torque & backpressure.

With respect - decatting an S2 will not require a live remap due to the loss of torque and backpressure.
Having born witness to an S2 being dynoed, having the cat swapped out and then redynoed all in the same building in the same morning - there was a slight increase in torque and bhp throughout the rev range.
The caveat is that on a Turbo, you can ditch the cat/centre resonator for a straight pipe but on the S2 if you remove the cat you must fit a central resonator otherwise you will reduce performance as you stated Roger.

1: you claimed a decat would require a live remap due to the loss of torque and backpressure. I said it didn't. You misread the sentence to suit your preconceptions.
2: yes. That's the whole point, the decat improves flow and performance slightly rather than hinders it as you wrongly claim.
3: performance was the wrong word. It will sound horrible. The resonator has nothing of great substance in it, maybe a bit of baffling around the central pipe.
At the end of the day, you'll argue until the cows come home if I don't agree with you anyway and he who shouts loudest isn't usually right. Take a look at any of the commercially available decat pipes for S2s and you'll see that they all incorporate a resonator rather than just a straight pipe.
I'll put you in touch with someone who has built exhausts for many of the 944 race cars (S2 and Turbo) and you can argue the toss with him directly. I will warn you that he might not be so accommodating of your points of view and will tell you that you're wrong in a way that the swear filter on here prevents me from doing.

That's a very poor attitude you have there, I was asking some simple questions and clarification from your statements, that's all.
Unyet you seem to of replied with an aggressive tone and suggestions about shouting, swearing and that's it's an argument ? !!
It's this sort of response that is totally not necessary, and only causes upset to the forum as per the recent Post regarding forum conduct.
Get off your horse and try and be a little or a lot more professional with your replies, this is a public forum.

I've asked some simply questions here, I can't see any issues with them unless I'm mistaken? then please explain ?
Back to the subject / thread subject: You've mentioned on the other decat post " A 'de-cat' will lead to a great deal of disappointment"
Maybe you could elaborate on this ?
Comments without any explanation are no good for any member to see and read, my post with the pleasant questions do NOT include any
aggression, or mention of starting a shooting match. If some members just enjoy picking fights all the time, I'm sure the administrators will agree they should go elsewhere for this type of activity.

My attitude isn't generally poor, I just accept that arguing with an idiot is a futile exercise as they will drag you down to their level and beat you with experience. The OP asked questions, I answered them - I don't see why I should have to justify them because one person can't read properly.
FWIW - I am known for being very helpful in my Region, regularly assisting others with 944s and generally most people's first port of call and only too happy to help. I strongly believe that everyone should enjoy their cars and feel supported and informed as to the upkeep of them or any enhancements they wish to make. I see far too much misinformation spread online, most of it being exported by the Merkins, I don't want to see it repeated here.
As I have stated before, Roger, I'm sure that you have the ability to contribute some of your knowledge and experience in a positive way to this forum. To quote Guardians of the Galaxy's Rhomann Dey: "Well, I don't know if I believe anyone is 100% a ****"

How Rude !
Lets try again, and see if you can answer nicely without any foul abusive personal insults (Which so far your getting away with)
Read this four times and then tell me that it's saying "you don't require a remap due to the loss of torque?"
Are you really trying to say
"you don't need to remap a S2 if you remove the cat because it doesn't lose torque and backpressure" ??
What was the cat swapped with, a straight pipe or resonator? and was there no loss from stock at all in any rev range?
So people reading this factual ? information need to take note that "removal of the cat will reduce performance unless a resonator is fitted" and not use a straight test pipe. Who makes this special resonator that increases the engines power
with no other changes? Only I'd of thought many other members would be very interested in this instant bolt on more power product (with no changes required) ?

Eldavo,
Foul abusive personal insults? What did I miss ? Did you edit your post or did the Mods get to it before I read it. From Roger's reaction I guess you must have called him a******************
or something worse.?
Surely you didn't criticise his strange vocabulary or grammatical incorrectness
This is after all ,the PCGB don't you know?
