   on my furio 1.4 basicly same as your westcoast but mine mk2 shape , ive currently got mk1 manifold and downpipe and a straight pipe from downpipe to a supersprint 2" back box and it pops all the time and once the engine is very warm its super loud lol i did have a sportex back box (same as your sniper , just different name) and it would quitely pop now and again
   
   theres nothing else really too it with it de-catted it should pop , my mates corsa c sri pops and thats just a cat back system so dunnoo but its a sign your engine isnt over fueling as no unburnt fuel is being wacked into the hot exhaust

   Take your lambda out, may run, may not. It will over fuel making it bang.

   to be honest if it aint going to pop it wont , just proves your cars fueling is spot on which is good even though you have a de cat ect... , other options get a custom map to make it run like shit and pop lol

   My VTR has a De-Cat Magnex system from the manifold back and even when hot it doesn't really pop, you get the slight little one when lifting off the throttle and a bit of a rasp but other than that nothing but a nice noise
   
   It's probably down to your fuelling being spot on, which is a good thing lol (I am guessing your system still sounds the dogs bollox though?)

    Mine pops with a cat or decat on, makes no difference really but then I do run rallye/xsi injectors. If you really want it to pop, try some larger injectors or a different FPR but it will overfuel

    I bet that's fu**ing loud with no silencer, no cat and sniper back box
    
    Sniper backboxes dont really pop very much, I would try to get a supersprint or kam racing backbox even though it will be a bit more quiet
    
    I've also gone 6 months without a lambda with no problems if u want to overfuel

    Oh its loud but wen crusing its not to loud, if unplugging lambda won't damage it I will do it i know it will just over fuel
    
    Oh maybe get a piggy back chip to make ecu overfuel

    Sure the 421, decat pipe and budget backbox "sniper" wouldnt of cost that or you got majorly mugged.

    You paid £700 for that lot?? More money than sense...
    
    Iirc if the exhaust is new, it needs to build up a layer of carbon coating before it will pop....could be talking crap but im sure I read this on a thread a while back.
    
    My Janspeed and 421 was virtually new and didn't pop but I have noticed a few in the last week or so and the inside of the pipes are now layered black.

    Heat wrapping won't really do much at all, best ways are as either different backbox or overfuelling
    
    You could change your standard fpr and put a 4 bar fpr in, but you will use about 30% more fuel

    Can't send links on my phone but search on eBay for 4 bar fuel pressure regulator, or adjustable fuel pressure regulator and set the adjustable one between 3.5 - 4 bar

    What do you do about blanking the hole left in the fuel rail though, providing its not using the FPR'd fuel pump setup?

    The fixed 4 bar is a standard replacement as far as I know, the adjustable one is a little more complicated, as you need to re-locate it to mount it on somewhere, due to size and weight.
    
    I got an adjustable one on mine but a mate fitted it so can't really help in that aspect sorry

    Pull away in 1st gear casually.
    
    Then let the engine over run at around 2800/ 3K RPM then casually change into second.
    
    This is the only way mine will pop. Its not until you start hitting high revs and changing gear, then mine pops.. I'm not too keen on that though.

    Doesn't matter too much, the FPRs fit either the rail or the in the pump setup above the tank. Can be a a bit tricky to push the one in the tank in though and get the clip over but nothing you cant do in 5 minutes and push it in with a clamp/caliper piston tool.

    Heatwrap will help slightly, it will keep all the heat from the manifold and will go out of the back so more pops. Well it worked for my mate, my mates corsa pops and bangs more than mine and it's a 1.2 but it's 16v and overfueling so that's why.
