maddog1982 Posted December 2, 2013 Share Posted December 2, 2013 so the blow is getting louder on my back box, looks like both tail pipes are leaking at the join. What are my options? Weld it up? new back box from Nissan or can I buy just an aftermarket back box? Quote Link to comment Share on other sites More sharing options...
coldel Posted December 2, 2013 Share Posted December 2, 2013 Most people that weld end up replacing within a year from what I have seen, if you dont have the cash handy, get it welded and save up for a decent aftermarket unit. Don't by the 'infinity' branded tat off ebay for 200 quid or whatever, if you want a budget unit spend the extra to get a scorpion or cobra back box.

MITZ@CougarStore Posted December 2, 2013 Share Posted December 2, 2013 Aftermarket options that we do, will have a new mid and rear, the Cobra resonated makes an excellent option over the Nissan system, for price, quality and sound, let us know if we can help...

Z-monster Posted December 2, 2013 Share Posted December 2, 2013 When I first bought my Zed I had to have that section of piping replaced by Nissan (Lucky it was done on warranty). It gets a lot of abuse through thermal expansion and contraction, combined with road filth, much, salt etc. The flange goes then the exhaust blows.

ZEUS Posted December 2, 2013 Share Posted December 2, 2013 I bought the tat off ebay over 2 years ago and had no problems at all with it Quote Link to comment Share on other sites More sharing options...
Briggsybriggs1 Posted December 2, 2013 Share Posted December 2, 2013 Same happened with me so ripped it out and fit a fat true duplex system in stainless steel :-) Quote Link to comment Share on other sites More sharing options...
GMballistic Posted December 2, 2013 Share Posted December 2, 2013 Cheapest option would be to buy some exhaust paste from Halfords and seal up the blow hole if it's not too big. This is only a very temporary fix though and won't last long. Welding your current exhaust is the next option but again won't last that long as others have said. Imo I'd stay clear of cheap eBay exhausts but that's up to you. If it was me, which it was about a week ago (my backbox was blowing in the same place), I'd get a full stainless steel exhaust system as it will last longer than the car itself and no more worries then. Obviously though that does mean spending some "big" cash but if your planning on keeping the Zed for any length of time then it's a worth while investment imo & will sound much better too. I'm getting mine from Tarmac Sportz ~ have a look if anythings in your price range is my advice; http://www.tarmacsportz.co.uk/products.aspx?CategoryId=32850911-9f8a-43e4-a5fc-24678e254d1d Quote Link to comment Share on other sites More sharing options...
gareth29 Posted December 2, 2013 Share Posted December 2, 2013 mines the same, thought i would cut off the 2 flanges and then join the 2 sections of pipe with a bolt-up sleeve - dont suppose anyone knows the diameter of the pipe? Quote Link to comment Share on other sites More sharing options...
