R31 Gagz Posted October 31, 2007 Share Posted October 31, 2007 (edited) Hey, Just remember someone saying how it would be expensive to modify the GTR and one of the reasons was it had dual exhausts so would cost twice as much. Basically what im getting at is the illusion that it comes with dual exhausts like a 300zx, looking at the below pic you can see that it goes to a single pipe halfway along and splits again at a T piece near the rear, so its not a true dual exhaust. This surprised me as I thought they would go a full performance dual exhaust being the performance/supercar car it was built to be, but instead it looks its small and restrictive and not what you'd expect to see on a turbo'd car. Its obviously good / flows enough though for the power it puts out. Anyone else have these thoughts? Cheers! Gagz PS..Does anyone actually know where it states what type of exhaust it is....diameter (2.5"??), material (titanium??), press bent or mandrel...etc??

okaythen Posted October 31, 2007 Share Posted October 31, 2007 noob question how will it matter if it's bent or mandrel ? Link to comment https://www.sau.com.au/forums/topic/191583-r35-gtr-dual-exhaust-myth-spotted-cool-features/#findComment-3446910 Share on other sites More sharing options...
Swiper the Fox Posted October 31, 2007 Share Posted October 31, 2007 noob question how will it matter if it's bent or mandrel ? mandrel bending does not distort the cross-section of the pipe...hence better flow Link to comment https://www.sau.com.au/forums/topic/191583-r35-gtr-dual-exhaust-myth-spotted-cool-features/#findComment-3446938 Share on other sites More sharing options...
funkymonkey Posted October 31, 2007 Share Posted October 31, 2007 when its not mandrel bent there are areas inside the pipe where the air doesn't flow smoothly, and can cause restriction. afaik the exhaust isn't titanium, which a lot of people have commented on... and are expecting aftermarket companies to come out with full titanium exhausts to drop the weight of the GT-R a little. Didn't notice the 2 to 1 to 2 layout of the exhaust... maybe we might see straight twin pipe exhaust systems pretty soon... or maybe the underbody layout doesn't allow for seperate pipes? Nissan did say they put a lot of effort into making sure the car was highly aerodynamic. Thinking something like this: Keep in mind Nissan would have done its best to cut down on emissions to meet Japan and the US's laws.

WazR32GTSt Posted October 31, 2007 Share Posted October 31, 2007 maybe the vspec and/or nismo versions get a true dual system they can't put all the goodies in the base model gtr now can they Link to comment https://www.sau.com.au/forums/topic/191583-r35-gtr-dual-exhaust-myth-spotted-cool-features/#findComment-3446979 Share on other sites More sharing options...
SS8_Gohan Posted October 31, 2007 Share Posted October 31, 2007 I thought it was mentioned somewhere that on the options list will be a titanium exhaust, reducing the weight by 10-15kg. Most likely will be standard on the "V-spec" and up... i think this was on the edmunds site man, soooo many cool things still to come from this car. JGTC, V-spec and more hardcore versions, Nismo versions, tuning house versions (Mines), all the aftermarket goodies... exciting times EDIT: tread pattern on those tyres are really interesting...

Bumblebee Posted October 31, 2007 Share Posted October 31, 2007 353kw isnt much power at all.... looks like the exhaust is the easiest way to gain another 30-40kw?

sh@un Posted October 31, 2007 Share Posted October 31, 2007 turn up boost. reckon there's a restrictor you can get rid of on this one?

Forged Posted October 31, 2007 Share Posted October 31, 2007 looks like the exhaust is the easiest way to gain another 30-40kw? I would bet my money on a "chip" or ECU reprograming to be most cost-effective performance gain for the new GTR. Look at two other modern twin turbo 6 engines; 997 Turbo gets an extra 50-55kw from a software and a Chiptorque piggyback can give a BMW 335i an extra 35kw at the wheels! Whats the secret? You know it. BOOST, FUEL and TIMING. Changing exhaust on these cars do help but not as much as a software. Remember this GTR was built without "the gentlemens agreement" in mind. I would expect the factory exhaust to be quite free flowing but relatively muted in sound.

R31 Gagz Posted October 31, 2007 Author Share Posted October 31, 2007 353kw isnt much power at all.... looks like the exhaust is the easiest way to gain another 30-40kw? I wouldn't say its not much power at all except in comparison to some very high power cars. I guess that system is good enough for current power but when you want to get serious power, an exhaust upgrade is definitely on the mod shopping list If I ever had enough money to get an R35 I would probably upgrade it anyway and maybe the air intakes depending on how good the stock ones are just so it could breathe easier, free up a few kws.

sh@un Posted October 31, 2007 Share Posted October 31, 2007 I know... I want it in my R32 to get rid of that nose heavy weight balance. this one is nose heavy anyway- the balance is reported to be 58:42 Link to comment https://www.sau.com.au/forums/topic/191583-r35-gtr-dual-exhaust-myth-spotted-cool-features/#findComment-3448198 Share on other sites More sharing options...
warps Posted November 1, 2007 Share Posted November 1, 2007 this one is nose heavy anyway- the balance is reported to be 58:42 That has to be a typo. Even the average FWD Avagnary has a better weight distriution than that. I'm thinking more like 48:52. Surely the Nissan engineers couldn't get the weight distribution so horribly wrong. It would handle worse than a 265 Centura.

djr81 Posted November 1, 2007 Share Posted November 1, 2007 GT-R's have always been horribly nose heavy. Why would this one be much different, gearbox location aside?
