350matty Posted March 16, 2008 Share Posted March 16, 2008 Hey i was driving my car today and put my put down then suddenly notice the car ehaust noise increase. I dont know what is going on but i hope its nothing bad. The noise increase is very noticable. My exhaust has even pops now, sounds like a modded exhaust its awesome. But i am concerned, i dont think its a whole in my ehaust. Where is all the popping coming from or why? Use to pop a bit before now its more often. Took it round to mates and he loves it, ive saved money on a getting a louder exhaust. Someone switch exhausts with me? or is the engine getting more aggressive cos ive not ragged it for a while? Thanks Quote Link to comment Share on other sites More sharing options...
AndySpak Posted March 17, 2008 Share Posted March 17, 2008 Hi Matty, Same thing happened to me just before Christmas. Turned out my back box had blown a big hole (actually the pipe between the back box and the join with the centre pipe had completely cracked all the way round...). The popping will be unburnt fuel hitting the hot exhaust and burning. I'd go and get it checked if I were you. You'll be losing performance, decreasing fuel economy and you might even be screwing up the ECU as it tries to compensate for the changes. Hope this helps Andrew Quote Link to comment Share on other sites More sharing options...

Dicky Posted March 17, 2008 Share Posted March 17, 2008 Same happened with mine (2004). Took it to the local exhaust dealer to have it checked out and he said this was a common problem on the Z. There is a flange connection between the back box and the piece of exhaust pipe running down the centre of the car to the engine Y section. The flanges on these two pieces bolt together. The flange, on the back box end of this connection, had broken away from the exhaust pipe. They cut out the complete old flange connection, made a new one from stainless and welded it in. Perfect job costing £120 if memory serves. The back box itself was sound, just as well because a new one was quite expensive (around £300 I believe) and would have taken a couple of days to be delivered Quote Link to comment Share on other sites More sharing options...

Hope this helps Andrew I hate taking it to the Nissan Garage the are balls. Ill see if i can take it somewhere else. Just booked up a trip to bacelona for fri so wont be able to sort it for 2 weeks noooooo. I hope i can drive it in the mean time. Loving the sound tho its just what i wanted. Ill get under and check for cracks. Hate problems! Have an 51 reg almera to nearly done 100k and nothing has gone wrong with it everything wrks perfect. But with the Z had lots of concerns, i feel like its fragile! Quote Link to comment Share on other sites More sharing options...

350matty Posted March 17, 2008 Author Share Posted March 17, 2008 y pipe back to and including back box Think my wish has come true really wished for my exhaust to sound louder and if it popped id love it got both without paying a penny for new exhaust haha Ill have a look, must be second hand for that price. May just get a nismo back box what i wannted for a while. Quote Link to comment Share on other sites More sharing options...
M13KYF Posted March 17, 2008 Share Posted March 17, 2008 nismo is a cat back system (y pipe onwards). Not just a back box and it wouldn't fit unless you bought the whole cat back system Quote Link to comment Share on other sites More sharing options...

I was lucky enough to find a new Nismo Zorst owner who let me have his back box for £80 (Thanks Mike )but the bit where yours had cracked was exactly the same place mine did. Mine was so loud, I was scared to rev it above 2,000rpm! I looked into buying a Nismo or other performance exhaust but they were all around £750-800 and this was a figure too high, unbudgetted in December...

How mush is it for an nismo back box exhaust? Quote Link to comment Share on other sites More sharing options...
AndySpak Posted March 18, 2008 Share Posted March 18, 2008 I don't think you can buy just a back box from Nismo, you'll probably need to buy a catback system and I think they cost around £750-800. I'm sure someone who has bought one can tell you exactly what they cost... Quote Link to comment Share on other sites More sharing options...
350matty Posted March 18, 2008 Author Share Posted March 18, 2008 This is my problem. But im happy how it sounds, it fantastic! Shame ill have to get it repaired.

tmJak Posted March 18, 2008 Share Posted March 18, 2008 have you considered getting a scorpian exhaust as in this thread? you'd be able to keep the sound and it's around £340 brand new Quote Link to comment Share on other sites More sharing options...

Stew Posted March 18, 2008 Share Posted March 18, 2008 As tmJak suggested. Scorpian for £300 odd..... Sounds nice to me! Not THAT much more than Dicky paid for the repair..... Quote Link to comment Share on other sites More sharing options...

Not much good with the old computer but I'll try to get a pic posted. Wish I hadn’t bothered taking the pic now cos its confused me. The st st bit seems to have been welded on the good end of the exhaust while the end that was damaged looks to be the original flange (which I know for sure was broken). Anyway this is the repair. Hope it helps and hope the pic size is ok as the original was to big and had to get my daughter to crop it for me. Quote Link to comment Share on other sites More sharing options...
350matty Posted March 24, 2008 Author Share Posted March 24, 2008 Cheers for the pic, looks fine. Yeah best off getting a weld job done. Think i can get it done for £10 according to a friend of a friend. Ill try get it done this week sometime. Quote Link to comment Share on other sites More sharing options...
