Exhaust whistle from turbo when you back off on the accelerator

hi
are you sure you haven't run over an umpire in your travels and he wants to give you a kick lol

Without turning this into a tech thread about turbo lag, back pressure drops, loss of performance, legalities and economy etc i'll simply say 'Yes" straight through exhaust will give you that noise.
Good luck!!

Yeah good hi flow muffler with 3'' dump pipe. You will need a good quality cat also. Many 3 litre Patrols with 3'' exhausts sound good, with alot of whistle, but it can get very annoying after a couple of hours at highway speeds.

Well my straight thru Mandrel exhaust doesnt sing, whistle, bark or play tunes.

Maybe Im going faster than the sound LOL

Perhaps a 3" may be a bit big for a D22 a 2 1/2 or 2 3/4 may be better.

Too big can be worse than too small.

Quietness is next to godliness when doing several hundred k's a day

May be I'm just getting to old ROFL

sounds fully sik bro

Not having a go at you Navara09, I know the exact sound your talking about as I have noticed it on a few patrols as well and also the video you are referring to watched it myself, have actually noticed it on some trucks to while there going through their gear changes, my mate did it to his paper truck, sounds good while going through the gears but drove me mad while shooting down the freeway at 110k.
