To decat or not to decat, that is my question

I bought my tuscan already decatted (longer header pipes) but with the standard rear cans, it was not a great sound until well on the throttle tbh, sounded muffled and puffy. So I sleeved the rear cans and OMG it sounds beautiful. nice and burbly at low revs but crazy when nailing the throttle. best mod so far and cost me 1 tenner and 1 hour in my lunch break

I have exactly the same set up (decat & sleeved cans). Sounds ridiculously good on all throttle openings - and completely feral at the top end! Probably louder than I would have chosen myself, but that's how I bought it and I am not changing it.Never too intrusive for me though on long journeys. Did 4000 miles around Europe the other year and not once did I wish for less noise. In fact I spent most of the time with the radio off and rear screen out just to enjoy it all the more through the mountains.
All a matter of preference at the end of the day of course.
Incidentally, mine will even legitimately go through it's MOT emissions test while decat as long as the engine has just been serviced, throttles balanced and is in good health.
What are my options then chaps?
Just picked up the Tuscan. It appears to have sleeved standard cans which from what i read should be loud but they are not. I get some pops but its very subtle. Lovely noise but i bought the car to be shouty!
So should I next go for some powertech cans, or perhaps go for a decat first and then see.
Hard to tell if there is much difference between sleeved stock and powertec cans by internet reading.
Btw im after artillery.

Shine a light down the cans, are they sleeved. If not sleave them. If you want to go further try Clive f decats Just picked up the Tuscan.

If so get yourself down to Peacock Farm on Tuesday for the Berks TVR meet and there'll be a few others to listen to.
You're welcome to pop over sometime and try my powertech cans just to see what they sound like as its only 2mins to swap them around.
My preference if you have the standard back boxes is for decat and sleeved std cans. I'm now on decat with act boxes and powertech cans and it's quite similar.

In that case, I presume you already know the answer Even full sleeving won't do too much (other than adding further weight to the already heavy original cans).
Powertech cans are in a different league, both sound & weight- wise. For "artillery", you will definitely need a decat.
Remove the back boxes on top of that- and "Guns of Navarone" springs to mind.

HiDid you make up a hangar to support the pipe as per the standard box or are they ok as the pipe is lighter?

Sagi Badger said:
Yep, made a hanger. Stainless flat bar, two of them at 90 degrees, welded together on the outside of the curve with the hanger cut off the box welded on. You need to as the weight of the can will twist it down/round otherwise.

Great thanks for the info. Did you notice any improved performance from removing the box or was it just the noise?J
Well. Sunshine and ebay is a dangerous thing.
Ordered some power tech cans.
Also booked a decat from racing green.
Clive F is around 250, RG can do them for 140? Not sure why the large price differece. Its just an empty pipe, cant imagine there is that much difference..
Powers advised a chip is good, Green advised a chip is not needed. Im going with not needed until deemed otherwise.

Yes there is. What you've ordered at that price is empty catalysts where the core has been knocked out. I can't remember which of the decat suppliers tested them, but the emptied cats flowed badly where the gases pass out the large aperture of the manifold into the wide chamber of the cat body and then need to squeeze out of the exhaust end exit which has virtually no transition to it diameter.

After 10+ years of owning a Tuscan S I've settled with a decat and the factory cans. I have CCC's as well but it made the car obnoxiously loud with the decat. Fun for a while but it got old. Decat And standard cans is plenty loud enough, gets lots of pops and bangs and the odd pop of flame if you're lucky, but is a much bassier tone overall which I prefer. Sounds much beefier than the sharp tinny rasp you otherwise get. I also think the standard cans are the best looking too.

If your cans have now been sleeved and you have then next step would be decat, and then it really will put a smile on your face. Just picked up the Tuscan.
