Going to have a LPG system installed on my Turbo Diesel Landcruiser for better economy power etc. A local installer and a SA distributor for another brand of system have told me that because I have a Turbo Diesel the main muffler can be removed with very little increase in engine/exhaust noise, and my vehicle will meet all legal requirements (Have a rear resonator). I understand that the turbo reprocessing the engine exhaust gases cuts down the noise.

The removal of this muffler on my 60 series will also increase performance I have been told on a Landcruiser site. A number of the LC site members have also told me of the very small increase in vehicle/exhaust noise on muffler removal on a TD and I appreciate their input.

BUT, I have not heard from anyone with a TD without a main muffler towing a heavy van (ours is around 2500Kg) and the affect this has on the engine/exhaust vehicle noise at various speeds.

If you have a Landcruiser TD 60 or TD 80 series on LPG without a main muffler towing a heavy van could you pass on your thoughts to me. Thanks

I will accept a straight thru system with a slight increase in noise and its performance gain, BUT she who must be obeyed may not and I would prefer not to have to revisit my exhaust system again after the LPG install.
