sam350z2013 Posted November 27, 2013 Share Posted November 27, 2013 Hi all, Wanted others opinion whether a new exhaust would increase or decrease fuel consumption?... I have been told mixed opinions 😄 Quote Link to comment Share on other sites More sharing options...
MITZ@CougarStore Posted November 27, 2013 Share Posted November 27, 2013 (edited) Probably increase fuel use as you'll be driving a lot more just to listen to it... Edited November 27, 2013 by CS 1 Quote Link to comment Share on other sites More sharing options...
Paddy78 Posted November 27, 2013 Share Posted November 27, 2013 Probably decrease as you'll be driving a lot more just to listen to it... What he said! It gets even worse when you add HFC's as well! Quote Link to comment Share on other sites More sharing options...
BulletMagnet Posted November 27, 2013 Share Posted November 27, 2013 If anything it would INCREASE when you drive it more, lol Quote Link to comment Share on other sites More sharing options...
Paddy78 Posted November 27, 2013 Share Posted November 27, 2013 Yeah, decrease MPG, increase fuel consumption. Quote Link to comment Share on other sites More sharing options...
r37 Posted November 27, 2013 Share Posted November 27, 2013 ive lost about 2MPG since getting my HFC's and invidia gemeni fitted. Had it remapped too so 1st, 2nd and 3rd are all redline gear changes. Worth it though. Quote Link to comment Share on other sites More sharing options...
bamdc2 Posted November 27, 2013 Share Posted November 27, 2013 Its a 350z so ignore anything to do with MPG! Get an aftermarket exhaust and enjoy the sound! 3 Quote Link to comment Share on other sites More sharing options...
drginger Posted November 27, 2013 Share Posted November 27, 2013 If you drove EXACTLY the same, would it not slightly increase it due to things flowing more freely? Just guessing, not saying this is right! Quote Link to comment Share on other sites More sharing options...
richmillions Posted November 27, 2013 Share Posted November 27, 2013 Probably increase fuel use as you'll be driving a lot more just to listen to it... This and I drive with the window down more further reducing economy (I think that's supposed to reduce economy by 5%) Quote Link to comment Share on other sites More sharing options...
r37 Posted November 27, 2013 Share Posted November 27, 2013 Probably increase fuel use as you'll be driving a lot more just to listen to it... This and I drive with the window down more further reducing economy (I think that's supposed to reduce economy by 5%) Below 30mph you lose 5% economy, around 70mph you lose 15% or so. Air con drops economy by around 10% across the board. Still worth it to hear the bark i get in second when flooring it at 3kRPM 1 Quote Link to comment Share on other sites More sharing options...
sam350z2013 Posted November 27, 2013 Author Share Posted November 27, 2013 thanks for the replies..

techinstaller Posted November 27, 2013 Share Posted November 27, 2013 as long as it takes to undo the rusted to muck nuts on the cats as ive just spent all day soaking them every hour with release fluid as im pooing my self that the studs will snap which are captive (welded )to the cats threads and ive a new milltek coming on friday.Also allow another £35 from nissan main dealer for the gaskets and bolts to bolt the new exhaust back to the cats as they dont come with the exhaust all the other bolts and gaskets do tho for the new sections.good luck Quote Link to comment Share on other sites More sharing options...
r37 Posted November 27, 2013 Share Posted November 27, 2013 took the chaps at horsham about 2.5 hours to strip my old exhaust + cats and refit new HFC's and invidia gemini. Everything came off pretty easy though. Expect to pay around 2-3 hours labour. Maybe £100 - £150 depending on if its a bugger to remove.

sam350z2013 Posted November 28, 2013 Author Share Posted November 28, 2013 Thanks ppl.. I'll ask around today for best fitting price. Also, is all that's needed is mainly just the exhaust to get a nice sporty tone from revs ? I just want mine to be a bit louder..😠Quote Link to comment Share on other sites More sharing options...
bamdc2 Posted November 28, 2013 Share Posted November 28, 2013 corbra/scorpion exhaust and get a popcharger. Job done. Would prob leave HFC as have seen they cause a few O2 sensor problems which kick off the EML. You could get y pipe but I have been more than happy with popchrger and scorpion exhaust. 1 Quote Link to comment Share on other sites More sharing options...
