Tuscan S Rear exhaust boxes

[netnewt]

Can't search topics for answer to this so appealing for help!

The exhaust cans on the Tuscan 2S (and probably other Tuscans too) attach to a short stub protruding from the useless rear boxes. I'm fed up with the stub weld breaking and my CCCs clattering down the road (though not as fed up as the drivers swerving behind me). These rear boxes are apparently useless - they contain no baffle material - so they're simply a weak point and I'd like to mod the exhaust to remove them. This would mean my cans can attach directly to a weld-less piece of pipe. I do not want to de-cat.

Has anyone done this? Is there an off-the-shelf solution available? Of course the S has the wider diameter pipes.

Of course another solution would be to provide some sort of strap supporting the weight of the cans but hardly elegant.

I think Racing Green sell or use to sell pipes that replaced the rear boxes. Failing that I don't think it would be that difficult for an exhaust specialist to make some pipes.

I had exactly this problem with my MK1 S to the point where the original sh*tty back boxes were beyond repair. I went to an exhaust fabrication centre and got them to cut off the back boxes and replace them with straight through pipes. As this then eliminated the rubber strap that supports the back boxes I got them to weld an "L" shaped bar to the side of the cans and install a rubber mount to the underside of the boot floor to support the weight of the cans (see pictures below) - I think it all cost about £150.


The problem that I had once this was done was that I thought it was too loud with the straight through cans as well. I drove it for a month or so and after a chat with Dan at Taylor TVR decided to buy the ACT system which is new pipes from cats right to back boxes in nice shiny S/S and far better quality than the originals - the sound now is far more bassy but still plenty of pops and bangs.

I still have the pipes that I had made up if you are interested in giving them a try I'm sure we could work something out to get them to you and if like the sound you could make me an offer - PM if interested.

All the best

Thanks both! I wish PH would sort their search.

Racing Green do indeed do a solution and I've spoken to them, but it's a lot of money and they have no pictures or videos of their solution.

The perfect solution is shown in the pic from The Surveyor in that topic though! Just a few inches of plain pipe.

Thanks, newt.

Thanks Paul,

That's useful info. I do like my car loud - and it is with the CCCs... I wondered what difference the removal of the boxes might make. It might make it too loud even for me - though you don't drive a Tuscan if you don't like being noticed! ;-)

Thanks also for the offer to try your original adapted pipes - but it would probably be as simple for to get the same done as you at my local.... and just mess with the end bit of the pipes. However I note that you have gone for the ACT which I think is the same as the one from Racing Green.

Newt - I did attach a few more photos on my original response but they didn't come out - here's one showing the can support brackets - I still have these on the car and they really do make the whole system rock solid so no danger of the cans launching themselves into orbit in future!

Coincidentally doing the same to mine on Monday.

Thanks Paul... got the pic

Who's performing the surgery nrick? Are you having the box replaced with a simple pipe or the whole exhaust changed?

[The Surveyor]

It was the best modification I did on my Tuscan, not because of the weakness in the back-boxes, but because of the great noise the car now makes..... woo hoo.

£160 for both sides done beautifully by Advanced Automotive Systems in Newcastle, nice guys who are very skilled with stainless

Is your car de-catted and what cans do you have?

I'm still running in my new engine but with the decats it's looking like sleeved original cans are the best sounding, but as i've already got some std (non sleeved), some CCC's and a set of half sleeved ACT's, my brain is at the point of not wanting to get another set that's different again!

I've got standard rear cans but they're fully sleeved. I've still got the cats in, I've been told that it isn't good for the engine to take the cats out and as my engine's done nearly 50k miles i'm not going to take risks! Taking the back-boxes off has the same vocal effect as a de-cat without the MOT worries. The only advantage of a de-cat would be the small reduction in temperatures which has never been a major issue.

For me, it's the perfect combination

Another for the ACT S/S system. On a mk1 Tuscan s, with cats and fully sleeved carbon cans. Seems a nicely fabricated system (no cans hanging off since!) and for me a nice exhaust note.

The other mods on this thread look a neat solution though so like with most things it comes down to personal preference.

[netnewt]

Thanks folks. I confess I'm a little concerned as I've finally achieved the sound from my Tuscan 2S that I love, and I wonder how it will change if I remove the rear boxes either with a "cut and shut" or by fitting an ACT solution. Here's how it sounds now:

In the video clips the loud pops and bangs come across only as little noises sadly though!

[B3NNL]

I have the larger bore ACTs, now they are bloody massive, but the sound is transformed.
Much more bassier and it doesn't scream like the standard cans. The only clip I have is as part of my vid I made, so there is a soundtrack although I did lower it for when I started up.
I'm doing a track day at keevil Monday, so have the standard cans on to pass the noise test. When I'm done, I'll chuck the ACTs back on and do some before and after, without the soundtrack.
Meantime, here's my first vid.
Car is still fully catted, only mod is the end cans.

Thanks B3NNL... that's a great video clip I must say. Is your whole exhaust system (forgetting the end cans for now) an ACT one from the cats without the rear boxes?

Nope, the only thing that's changed is the end cans, everything else is still standard. Imagine what the whole ACT system would sound like!

We are having a go, I have a weld that is breaking so it has to be done.

I have the option on a custom made exhaust as well in stainless, big 's' bore but haven't the time, money or desire to do it right now, might be a winter job.

I am going to do a video on it, hopefully it should be ok. Decat, std boxes and remove the rear boxes, now lets see how that sounds!

[Walford]

[nrick]

Finally got around to it (removing the back boxes), I know it won't be for everyone but I love it. Haven't got it quite right yet, but the noise is very deep and simply great (for me).

Decat, std cans and no boxes.

Pardon?
