neo-ninja Posted February 8, 2011 Share Posted February 8, 2011 Hi All, Just had the car in MOT, and I did think recently it was making a slight rattle when pulling away in low gears. But service is due soon so didnt think about it. However garage doing MOT have called and said that the join where the pipe joints the back box is nackered. he has said they can wield will prob be an hours work he recons to do, but he says he has no idea how long it will last, if its only going to be 6 months, or 2 years. or he said he can price up new one. I was wondering if anyone can offer any advice, and recomendations ideally asap. Thanks Quote Link to comment Share on other sites More sharing options...
martinmac Posted February 8, 2011 Share Posted February 8, 2011 Its a common fault and welding is a good fix. I wouldnt let him order a new one, the traders on here can get you one a lot cheaper. I would get it welded and then look at an aftermarket replacement. Quote Link to comment Share on other sites More sharing options...
neo-ninja Posted February 8, 2011 Author Share Posted February 8, 2011 Ah ok cool, you recon getting wielded is worth doing at least for a decent amount of time. Quote Link to comment Share on other sites More sharing options...
martinmac Posted February 8, 2011 Share Posted February 8, 2011 A lot of people have had it done ind it will last you a while until you decide what to fit. Its a weak joint so once its welded you will be fine. Quote Link to comment Share on other sites More sharing options...
glrnet Posted February 8, 2011 Share Posted February 8, 2011 Definitely, mine had the same problem and lasted at least 6 months, in some ways you could argue that the weld may even be stronger than the original metalwork. I'd get it done, get through the MOT and then decide if you actually want a new exhaust, there's loads of info on here from loads of members for all sorts of cost options Ah ok cool, you recon getting wielded is worth doing at least for a decent amount of time.

neo-ninja Posted February 8, 2011 Author Share Posted February 8, 2011 Brilliant thanks guys, i think i will see what kind of price he comes back with for doing a whole job just for future refrence! Quote Link to comment Share on other sites More sharing options...
neo Posted February 8, 2011 Share Posted February 8, 2011 mine cost me £20 to have welded, lasted about a year, then had the joint cut out and a new stainless steel sleeve put on for about £50, good as new now even tho looking from the rear the back box isn't level Quote Link to comment Share on other sites More sharing options...

But brilliant suggestion. They have quoted me about £50 to do it but which isnt too bad i didnt think. "wielding" Quote Link to comment Share on other sites More sharing options...
neo Posted February 8, 2011 Share Posted February 8, 2011 to be honest you get really notice the levelness that much but it is slightly uneven Quote Link to comment Share on other sites More sharing options...
Rob_Quads Posted February 8, 2011 Share Posted February 8, 2011 I would get them to weld it up, should be good for a good 6 months. In that time keep an eye out for a second hand backbox on the forum. Exactly the same happened to me. Quote Link to comment Share on other sites More sharing options...
neo-ninja Posted February 9, 2011 Author Share Posted February 9, 2011 How much should i be looking to pay for a backbox? If i want an OEM one. Quote Link to comment Share on other sites More sharing options...
evest Posted February 9, 2011 Share Posted February 9, 2011 How much should i be looking to pay for a backbox? If i want an OEM one. Nissan will charge you in the region of a £1,000,000 for a new one. Elsewhere prices vary upto around £300 (I think) - money which could be better spent on a lighter, shinier, better sounding upgrade!! I had my OEM backbox welded at around 50K and it lasted until 75K. Quote Link to comment Share on other sites More sharing options...

I had my OEM backbox welded at around 50K and it lasted until 75K. Im on around 46k so hopefully it lasts that long as i do around 6-8k miles a year. What is wierd now i have got it back is how much quieter but more refined the sound it! It must have gradually gone over time then suddenly gone as i dont really remember thinking "wow this is really noisy compared to yesterday" (I drive the car daily) But it definatly sounded a heck of a lot noiser but not in a gone exhaust way more of a meatier muscle car way. But now it sounds much more refined so not bothered eitherway. Thanks for the advice everyone! Quote Link to comment Share on other sites More sharing options...
Chris`I Posted February 9, 2011 Share Posted February 9, 2011 Always a shame when you get them welded as they dont sound as good! Just have to upgrade to a new shiney one Quote Link to comment Share on other sites More sharing options...
neo-ninja Posted February 9, 2011 Author Share Posted February 9, 2011 Sooo gave the car a spin, and sounds considerably less beefy but yet feels more sharp and a little more powerful, is that even possible? Have had a chance to give it real burst of power yet will be interest to see next dual carridge way i get to. Quote Link to comment Share on other sites More sharing options...
