Decat DP = Louder turbo ??
Just fitted a Decat downpipe to my P1 and noticed that the turbo spool up is alot louder, quite pronounced even at low revs. I dont think the exhaust is blowing at all, is this normal?
Thanks

Im talking really quite loud, spoolup sounds like a diesel transit, but in a nice way. lol even below 3krpm or off the throttle i can hear the turbo spinning.
Yours the same?

It'll be louder and you'll hear it start working earlier- the benefits of a decat mate! As long as its a whooshing sound and nothing nasty sounding all should be well with it!

PS, have you got a KL? P1s can run lean on a decat sans remap!

Yeah its been remapped prior to the DP @ Powerstation, and i fitted a knocklink today, rarely lights first green LED.
Guess theres nothing wrong then, just surprised of the difference in sound.

There is a lot less restriction after the turbo thus it spools up faster, the new down pipe is probably stainless steel I assume which also has very different acoustic properties to mild steel..
We have a decat down pipe, the turbo spools faster and is very audiable.. it sounds gorgeous.
