Nick Jones Posted January 27, 2013 Share Posted January 27, 2013 I did repack a stainless aftermarket Vitesse back box. It wasn't old. The problem with that one was partly yards of sticky tape that had been used to hold the SS wool and alumina blanket onto the perforated pipe during the build had melted from exhaust heat and formed an impermeable layer, isolating the sound absorbent material from the passing gasses and partly that the ss wool was extensively sooted up.link to story http://sideways-technologies.co.uk/forums/index.php/topic/761-silencer-building/page__p__9859__hl__silencer__fromsearch__1#entry9859Nick Quote Link to comment Share on other sites More sharing options...

They are looking great but I was shocked to see I can look right through them.... Is this normal? Shouldn't there be any muffling taking place?Did I buy the wrong ones?Thanks,MichelDoes it fit though? the bends in mine were a bit out so the Y sat about 6" lower than it should of.RR Quote Link to comment Share on other sites More sharing options...

RedRooster Posted January 30, 2013 Share Posted January 30, 2013 Looks a better fit than mine was, have you a picture from the front to show how much the Y section hangs down? RR Quote Link to comment Share on other sites More sharing options...

RRI'll try and get one for you, I think a lot of it stems from the front manifold it gives a good starting point leaving the rear section hanging very nicely in the central recess of the chassis.

FGRob Posted January 30, 2013 Share Posted January 30, 2013 These are the two boxes fitted but not clamped - I'm going to use Mikalor clamps as they don't rust and seal a whole lot better Quote Link to comment Share on other sites More sharing options...
RedRooster Posted January 31, 2013 Share Posted January 31, 2013 Thats a pretty good fit, like you say the first join onto the LCB is critical, it'll be interesting to see how much clearance you have once the cars back on its wheels & settled.I'm also using those clamps, well i would be if the things ever turn up in the post!RR Quote Link to comment Share on other sites More sharing options...
Dicky Blighter Posted January 31, 2013 Share Posted January 31, 2013 You would be better off fitting carpets than that laminate flooring though, bugger to get it cut around the tunnel and makes the car a bit noisy. I think you have bought a bit too much - could always use extra to retrim dash and make some door capings Quote Link to comment Share on other sites More sharing options...

I wrapped this aroond the baffle,to make a bigger air gap,so it would no clogg up as easy agen. then tack welded in a few spots, and masticated the rest, just incase i want to get back in, which will be very easy nooI done the mods. It aint leaked at all, and they are alott lott quieter .Maybe food for thought for some up an coming tinkerers of tinkered things, that need to be tinkered wid. MHi Marcus - what type of mastic did you use to seal the exhaust. Tempted to do similar with mine.CheersDoug Quote Link to comment Share on other sites More sharing options...
GT6 M Posted February 4, 2013 Share Posted February 4, 2013 Doug,just a ordinary black silicon mastic. most will withstand the rear box temp.think it had on 120 Degs, they been done a while noo, no sign of any leaks at all.If I dooing it agen, I think I would just use a few SS screws, and a couple of small plates to bridge either side.this way you no need to weld up. maybe handier for some one wid ne welder.To cut it open, I used a fine cutting disc, just make sure ye cut a bigg enough hole, so it bends back easy.plus, its alott easier working in a bigg wol, than a laal wolM Quote Link to comment Share on other sites More sharing options...
