Title: Rear silencer
Post by: velcro on December 05, 2009, 21:45:37: When i bought my 95 disco 1 (3dr) it had no rear silencer. Is this an MOT failure?

Also, is the rear silencer a seperate part or will i have to replace the mid section as well.

150 - are you sure?

A whisper is about 20 dB. A normal conversation is typically from 60 to 70 dB, and a noisy factory from 90 to 100 dB. Loud thunder is approximately 110 dB, and 120 dB borders on the threshold of pain.

Post by: velcro on December 08, 2009, 09:11:42: How about bumpers? Mine currently has no front or rear bumbers. Will I need to get some sorted to get it through the MOT? Planning to get a rear one soon but quite like the look of the front wthout one :lol:

Post by: Disco Matt on December 08, 2009, 11:27:38: I think you might need one to cover the projecting chassis ends, not 100% sure but I think they might fall foul of the regs relating to parts of the vehicle that might injure.

Besides which it'll look a lot better with one of those challenge-spec tapering winch bumpers on (even if you don't fit a winch) than it will with nothing at all!
