My main concern with doing track days in the R500 Duratec are the noise limits. I'd read a lot about other owners experiencing difficulties with noise limits, especially drive by noise rather than the static tests and potentially being black flagged and subsequently 'thrown off' the track day. Having paid a fair few quid for a track day, and more than likely having driven a hundred or so miles to get to a circuit, this wouldn't go down well with me... So... thinking prevention is better than cure, I decided to invest in a raceco exhaust as these have been recommend on blatchat, and by other R500 owners as being great for reduced noise without any reduction in performance due to the way they are made and packed.
Raceco Titanium Exhaust
I got in contact with Mike Riley (the new owner of the raceco brand)... he's been the guy making them for ammo for the last thirteen or so years, so the right guy to speak to. He recommended the 7.25" / 185mm diameter silencer which is a standard length with a 750mm sleeve and offset inlet pipe for the Duratec based exhausts. I paid upfront, and he manufactured the exhaust over the last couple of weeks.
Some pictures below of the components before and during manufacture.

Mike's been great advice and help, has done a superb job, and the quality of the exhaust looks excellent. A link to his site is here http://www.raceco.com/silencers.html
Getting a Titanium Exhaust Polished
I was initially a little against a titanium exhaust purely due to aesthetics - as I really loved the look of the shiny polished steel exhaust I currently have, so looked into getting the raceco exhaust polished. It turned out being titanium (which can be a fairly difficult metal to work with) there were hardly any polishing companies interested in taking on the job. After numerous calls I was recommended M&M Polishing in Poole. I gave them a call, spoke to Mark there... he was a little unsure due to the size of the exhaust and quality of titanium that would be used, but agreed to take a look at the silencer, test an inconspicuous area and take it from there.
So I arranged with Mike at raceco that once he'd made the silencer, he'd then deliver it direct to Mark at M&M polishers for inspection and (hopefully) polishing.
Mark at M&M received the exhaust a week ago, and as they were working with titanium they said it is always a good idea to find out first if it has been alloyed with another material such as aluminium, iron, copper, steel and so on. They tested an area first (in a place that wasn't noticeable) to see how it reacted to a light linish and mop.
