I see a lot of posts about sleeveing exhausts. I’m not sure what this is. Is it done on the centre box or on the tail pipes? Is it easy to do? Is it possible to get a louder noise with pops and bangs by just replacing the tail pipes? I dont even know what sleeveing involves. Any help or advice would be great. Is there anywhere in the midlands that do it?
It's the cans that are sleeved. May be easier to buy the sleeved cans and keep your unsleeved for track days etc http://www.ebay.co.uk/itm/TVR-TUSCAN-SAGARIS-CARBO...

Pretty easy to DIY...IMHO!Sleeve the carbon/standard (rear) cans by inserting some 51mm OD thinwall stainless tube into the can. This should be a reasonable interference fit - and as you tap the new tube in you'll see it gradually covering the perforated internal tube of the original....effectively negating the sound absorption of the standard can.
If you're de-catted, the noise is a bit OTT for long runs - in my opinion.
Just find a local supplier of the stainless tube, get it cut to length (500mm for each side, if my memory serves me right), then un-clamp each can and with it on the bench tap the tube in. A bit of silicon grease may help tapping the new tube in.

I’ve got no cat and sleeved cans. Just had the interior done and completely sound proofed the interior so that long runs don’t result in my ear drums seeping claret!
The sound can be a lot of fun, but can be extremely antisocial!!!! I mean, I can’t even do track days because the car gets a prohibition order slapped on it for being too loud.

When i did mine i used a cheaper version of dynamat and then some relatively thick acoustic foam. Dynamat and similar products work better on metal bodies as they're designed to dull the resonating effect of a panel. Fibreglass doesn't really respond in the same way so a combination of both seems to do a better job in my experience.
One of the better things I did was to put it on the back of the door cards as that had a great impact and reduced the sound levels in the cabin.
