Haven't heard one on a falcon though. 1 Link to comment Share on other sites More sharing options...

Bonjaz Donating Members 1,841 Member For: 16y 8d Gender: Male Location: CQ Posted 20/03/14 11:45 AM Share Posted 20/03/14 11:45 AM Yea I have watched all the YouTube vids and they don't do it justice, it really does quieten it down. The only thing I would be worried about on a falcon is having it on quiet mode and forgetting and giving it a boot. An ss back pressure isn't much of an issue, but if I have learnt anything from this forum back pressure on a falcon is very important haha 1 Link to comment Share on other sites More sharing options...

Obviously would have the tune done for varex open, but if you boot it with it closed and the restricted path what might it do? Link to comment Share on other sites More sharing options...

LU82 Bronze Donating Members 569 Member For: 11y 10m 21d Posted 21/03/14 04:05 AM Share Posted 21/03/14 04:05 AM Sounds like a good set up. Would the boost referenced flapper affect times at the strip ? Im guessing the flap would open when building boost while on the brake. Is there still a noticeable exhaust note under normal driving conditions and while cruising on the freeway?Im not a big fan of noise its the main reason I still run the standard cat back exhaust. It doesn't seem to be holding my car back too much with the standard fg turbo. But once I upgrade my turbo it will become an issue. Link to comment Share on other sites More sharing options...
