A friend of mine that works for GHB construction is going to volvo school . They were telling him by 2010 cat will not be able to meet apa standards for road trucks and thier machinery . they will be replacing thier engines with Detroits Commings an volvo engines The new volvo engine will not be able to be worked on because they are not making any extra internal parts. they will be a throw away engine. The muffler for this engine will cost about $2,000 dollars because it has a after burner in it to reburn excess polutions. the exhaust will burn about 1500* an will be built from stanless steel Has any one heard any thin about this
