deankenny Posted April 10, 2013 Posted April 10, 2013 Im getting a new Y-Pipe and was wondering apart from only getting stainless steel, is there anything out there i should not buy? or anything which in this category would give any performance boost ? Quote
KC350Z Posted April 10, 2013 Posted April 10, 2013 (edited) stay away from jap speed also cobra y pipe is a good option as no flexi on them if decat but still want mot friendly the one with the race cat build in is good but not cheap wasso has one ill Motordyne XYZ Pipe Edited April 10, 2013 by KC350Z Quote
RobPhoboS Posted April 10, 2013 Posted April 10, 2013 If it's any use I've just ordered a Stillen y-pipe from Tarmacsportz I didn't want flexi's in there but let's see how easy it'll be to fit now Quote
MITZ@CougarStore Posted April 10, 2013 Posted April 10, 2013 The Cobra Sport Y Pipe we offer fits perfectly, a direct replacement for the OEM Y Pipe, which can be seen here - http://cougarstore.co.uk/index.php?main_page=product_info&products_id=112&zenid=7a960865758355d41783070083acd988 The above is less restrictive than the OEM system, so a great replacement... Please do let us know if you need any further information... Quote
Paddy78 Posted April 10, 2013 Posted April 10, 2013 Probably won't get any boost without a remap... Stillen, Cobra or Motordyne xyz all seem to get good reviews. or for info as they both sell these. Quote
MITZ@CougarStore Posted April 10, 2013 Posted April 10, 2013 Cobra Y Pipe against a damaged Nismo Y that we supplied and fitted a few weeks back... Quote
RobPhoboS Posted April 10, 2013 Posted April 10, 2013 Have you got a pic of the standard one without the shielding surrounding it ? Quote
MITZ@CougarStore Posted April 10, 2013 Posted April 10, 2013 Have you got a pic of the standard one without the shielding surrounding it ? Hi Rob, I do have a photo, will need to get it found and I'll post it for you... Quote

deankenny Posted April 10, 2013 Author Posted April 10, 2013 well i have high flow cats fitted, not a decat So i think the cobra one is my best option What is the price on it ? Quote

KC350Z Posted April 10, 2013 Posted April 10, 2013 check on the traders sub forums few sell them just depends whos the best for you and where you are Quote
Tarmac@TarmacSportz Posted April 10, 2013 Posted April 10, 2013 If it were my car I would get the Stillen, Flexis are the biggest fail point on a Ypipe and the maximum warranty you will get is 2 years (Cobra) most like Nismo only offer 12 months as they know they don't last. The Stillen Ypipe has no flexis and is the only Ypipe that doesn't. I sell both but the Stillen is more popular. Quote
RobPhoboS Posted April 10, 2013 Posted April 10, 2013 You should hear the horrible racket coming from my one at the moment Cant wait to fit it ! 1 Quote
Watshot Posted April 10, 2013 Posted April 10, 2013 I think some people may be confused about the function of the flexible part of any exhaust. It's not there to make fitting easier. It allows for movement between the engine and exhaust system. Before 'flexis' were common, the repetative twisting from the engine would fatigue a given point in the system which would inevitably split requiring repair or replacement. A flexible section at this stress point actually lasts longer than a solid section which may transfer the stress forces to another part of the system. 2 Quote
RobPhoboS Posted April 10, 2013 Posted April 10, 2013 Good bit of info Although I've not heard\seen reports of issues using Stillen. Quote
gsexr Posted April 10, 2013 Posted April 10, 2013 Got to be honest with my thoughts and they are if nissan spend money on R and D and decide flexi sections are needed then i would rather have them. As mentioned before they allow for some movement and without having them you might start getting vibrations through the car. Quote
Tarmac@TarmacSportz Posted April 10, 2013 Posted April 10, 2013 I wouldn't be overly worried about Nissans R&D, if they were trying to design the best and most functional exhaust system for the 350z then I think they could have come up with something a bit better than the OEM systems for both the 350 & 370z but with most things costs was probably more of a concern over optimal performance and longevity.. If Flexis lasted a long time then I don't think I would sell as many replacement Ypipes as I have, like I say no one warrants them for longer than two years and I've seen them fail on Nismo systems within a year that's why I would personally choose or recommend a Stillen, entirely up to the customer what they choose.

I thought calsonic designed/manufactured the exhaust systems for Nissan? Quote
MITZ@CougarStore Posted April 10, 2013 Posted April 10, 2013 Most flexis tend to fail as a result of them being part of the lowest part of the Zed, so they get caught on driveways, speed humps etc, we see it all the time when we work on 350zs in the workshop... This is what causes them to fray and then leak... 1 Quote
Tarmac@TarmacSportz Posted April 10, 2013 Posted April 10, 2013 Correct, same as Renault make the engine but it all comes under the Nissan badge.

Isnt it a VQ engine in the 350z designed by and made by Nissan in Japan, but used by Renault due to the amount of awards it won. Quote
TOM'S_ZED Posted April 12, 2013 Posted April 12, 2013 So what Renault does the VQ have a home. I was under the impression that although Nissan are partners with Renault the 350z was a purely Nissan.Also off topic I haven't looked to closely at this but do you think the 350z was a bit of a test bed for the R35 GTR .

RobPhoboS Posted April 20, 2013 Posted April 20, 2013 Just had the stillen y-pipe fitted, zero issues - straight on Quote
