marzman Posted March 15, 2009 Share Posted March 15, 2009 Hey guys, I picked up the K1 Andyvvc was selling on Thursday night, and had it fitted yesterday for £30. I wanted it loud, so i fitted it without the bungs, and then went for a drive... i was like 'on dear, what have i done?' It sounded ridiculous! It was shaking everything in my car and was basically un-driveable...! So, i fitted the bungs in the afternoon and all i can say now is - wow! It sounds like a 1960's mustang... its awesome! Its loudest at 2k revs, very very deep, but then when going fast it gets quieter which i like, and it sounds absolutely ace! So, many thanks Andyvvc... will hopefully see you in Wales in May.. oh, and his new exhaust looks and sounds Some pics... Quote Link to comment Share on other sites More sharing options...

Ekona Posted March 16, 2009 Share Posted March 16, 2009 With bungs it was measured at 87dB IIRC, and without it was touching 103dB I think. Those numbers may be within plus or minus 1 either way, I just remember that it was silly quiet with the bungs in but just below the 105dB max with them out. Those measurements were taken at 0.5m at 45 degrees from the RH outlet. You'll fail the drive-by at Bedford with bungs in should you ever want to go there though, and Goodwood's a definite no-no, but you should be fine for everywhere else.

Tim (Lomoto) had 102dB out of a Nismo with HF cats @ 5000RPM. 87dB sounds low, even with bungs. Must be doing their job! Quote Link to comment Share on other sites More sharing options...
Ekona Posted March 16, 2009 Share Posted March 16, 2009 Sorry, should've said that was at 3/4 max revs, so about 4.5K rpm on mine. I thought it was a bit quiet as well, but I've done my own tests with two different track-day spec noise meters and they all came out the same. It really is surprising how much noise the bungs do remove from the exhaust, but if you consider that every 3dB is a doubling in volume, then without bungs the K1 is over 5 times louder Quote Link to comment Share on other sites More sharing options...
andyvvc Posted March 16, 2009 Share Posted March 16, 2009 Glad you like it mate As i said, if the bungs arent quiet enough at motorway/everyday speeds, then you can always put some sound deadening into the boot cavity. The Zed has bob-all sound deadening as standard. I found a little Dynamat and some carpet muffles road noise wonderfully. My new system is bedding in nicely now, coking up a little inside so the slightly mettalic rasp has been replaced by a more aggressive V6 growl/bellow (depending on revs of course) Quote Link to comment Share on other sites More sharing options...
S1 HNK Posted March 16, 2009 Share Posted March 16, 2009 looks very chris, look forward to hearing it on saturday. I'll probably hear when you set off from macc Quote Link to comment Share on other sites More sharing options...
