If you're looking to get rid of "drone" and volume you might look at putting on the stock dps.

Its not gonna help. I have stock dps and start up sounds the same. Its not that loud but op wants something even quieter so he's gonna need to replace the exhaust or add resonators.

which version of the jb4 do you have? it will only affect coldstart noise on the newer ISO. the older ones won't alter wastegate position until the car reaches operating temperature.


head on over to n54tech and they'll clear things up for you within a few minutes. higher lagfix/wastegate position value = quieter car until you go WOT.

Thanks again guys for your help in this! I am quite a starter in this and having this forum as a help, is great!

I was totally happy with the setup I had before the Remus (downpipes, JB4 and stock exhaust).

My JB4 is G4 and with stock firmware from October 2012; not sure which exactly... Having help to the noise by modifying via JB4, would be great - need to try getting help from n54tech forums!

In addition, I did already order Vibrant resonators and will have them delivered next week. Hopefully that helps as well!
