Just out of curiosity , if you have a bung in place does it negate the effect of removing cat's as it restricts flow out?

Would a HKS silent system be a better solution to this sort of issue?

that makes sense, but i'm just wondering if it will actuall.y harm the engine ro turbo... have heard stories previously relating to too little back pressure causing issues with turbo oil seals as the lack of pressure allowed the oil to escape or seal to move causing wear... more urban myths?

Is there any recommendations for angled exit exhausts for the newage guys ??? must admitt kinda like the look off an angled back box won a car when all shined up !!

so far the Ninja 2 / racebox is winning, anything else worth considering that would not be OTT noise wise with full decat if neccesary and not require a bung in place to live with ??

[QUOTE=midnight;10212062]I dont quite get it , as when the bung is fastened in to the nur spec r, you cant see it ,as it is right down the tailpipe,which still gives you the 4.5' tailpipe unlike the afterburner vortex where the bung is fixed right at the end of the tailpipe and that really does look **** as it too has a 4.5 ' tailpipe with a smaller diameter hole in the bung than the nur spec bung.


Should have gone to Specsavers

Anyone who can confirm this? If were to happen though wouldn't it be solved with a remap?

markb_s1

if the issue was caused by the exhaust beeing more or less freeflowing than the previously installed one, yes, a remap would sort it.

IF, however, (and that's a pretty big if IMO!) there's any truth that excessively free flowing exhausts with too little back pressure cause oil to seep fromt eh turbo's oil seals, then i can't see how a map change would help.

I have a Genome backbox for sale if you are interested? There is a few youtube clips if you want to hear what they are like.

That sounds sweet mate, i,ve got a fully decatted vortex on my newage and it's a little ott but yours sounds much more subtle in this clip. I'm thinking a resonated centre section and a ninja 2 backbox
