Regular Fast Fleet readers may recall that I have something of a carbon fibre fetish and have added some carefully chosen embellishments to Godzilla 2 crafted out of the black magic stuff. I was particularly keen to fit the positively sensual carbon sleeved exhaust tips that Akrapovic make for some of their titanium exhaust systems, but the set for the GT-R were not available at the time I bought my system. However as soon as they were available earlier this year, I pleaded with the factory into swapping my titanium tips for them.

Measuring (like the Ti tips) a massive 5 inches across, but amazingly light, the tips are titanium but with a special carbon fibre sleeve designed to not deteriorate even when subjected to the high temperatures that Godzilla’s fiery breath can generate.

Akrapovic carbon tips

I had a chance to show off the new tailpipes at the superb Wilton House Supercar Event in August (write up here: http://www.evo.co.uk/news/evonews/271828/2011_wilton_house_supercar_gallery.html ) where we joined a group of 170 supercars on the annual charity fund-raising bash and I had a chance to tackle Gurston Down hillclimb.

One interesting development in GT-R tuning circles has been the cracking and copying of the 2011 model’s superior Transmission Control Module gearbox programming. The effusive praise a certain TV presenter has heaped on the “new gearbox” in the 2011 GT-R should actually have all been credited to revised software as the hardware is identical across the two models. Cobb Tuning released the software for their AccessPort tuning device and on advice from Cobb guru Ben Linney of www.gtc-r.com , I downloaded the update over the internet and used my AccessPort to upload it to my GT-R’s TCM.

Having driven a couple of 2011s I knew roughly what to expect, but it was still a revelation to have even faster and smoother shifts in my 2009 car. It now pulls away much more smoothly from rest at slow speeds too, and the biggest improvement is the ability to select 1st gear manually whilst slowing down approaching a junction or roundabout; something that was at best a rather hit and miss affair with the original software.

I had a chance to try out the “new gearbox” at the Nurburgring at www.trackdays.de ‘s last event of the year in late September. Godzilla 2 behaved impeccably, with the 400mm Alcons soaking up even the hard braking at the GP circuit which was open to the public the evening before. The actual Nordschleife track day went very well apart from a heart stopping moment at 120mph when I got distracted by a very well driven GT3 RS and completely missed my braking point: http://www.youtube.com/watch?v=kGV-RE_myPc

As I say in the video “in any other car, we’d have been straight into that barrier”... Thank you GT-R.

I'm not a huge fan of the flame-blued titanium tips. This is a welcome change. Have to see how long it stays shiny and "unburnt"

Gurston Down was about ten mins from my old place, great fun but very short!

I think you need to worry about the effect that lightening the tips of the exhaust will have on the balance of the car. :-)

Those look awesome Yu...

CF can on a bike is the optimal material for that application and provides a measurable performance advantage though, no? On the one hand you could say indeed CF tips on the Titanium exhaust are X grams lighter and therefore provide a functional superior solution regardless of their aesthetics. On the other hand the objective difference in performance is likely not significant enough to be measurable and the only reason to have them is aesthetic. I guess it falls into the same category as Porsche's sticker bonnet badges and Honda's NSX-R shift boot mesh. What is cool and what is not is almost entirely subjective. BTW Love your car (except for the exhaust tips) ;-)

But it's not carbon fibre "look", it's real carbon fibre! Ever seen a CF Akro can on a MotoGP or superbike? Same thing. I agree, I would never put fake CF on anything.

Yes it looked fantastic wrapped in evil purple. I debate the aesthetics of the carbon fibre "look" though when the carbon of the item is non functional. Titanium exhaust, awesome! Kudos for ponying up for such an expensive mod.* but what about a titanium "look" exhaust? It's all totally subjective of course, I'm of the opinion though that carbon fibre in and of itself is not a particularly pleasing look UNLESS it's inherent functionality is also on display. Carbon fibre panels and body structures, cool. Carbon fibre "look" plastics, panels and exhausts.... not so much to me. *I still have the "death of Godzilla" issue of PC "somewhere" I think. So sad.

You know this car was wrapped for a year, right? And the Akrapovic added a dyno-proven 24hp (30hp max gain) whilst saving over 17kg in weight. The carbon tips even weigh a few grams less than the double walled Ti ones. Nothing wrong with them looking good at the same time...

On a instrument as brutally/beautifully functional as the GTR fripperies as ineffectual as carbon fibre clad titanium exhaust tips seem the height of ridiculous to me. Akrapovic titanium exhaust, height of techfetish nerdcool. Akrapovic branded carbon jewelry, tacky as a fake carbon vinyl wrap. And at least the wrap would be useful in saving your paint.
