New Injectors and Gauges...Now more Exhaust?
 

So I am getting new Bosch Injectors, Boost and Egt gauges installed after harvest but I am wondering about a bigger 4 inch exhaust to replace my 3inch and dual 2.5 inch tail pipes, anyone else make the switch from 3 to 4? Do you like it better?

and whats the deal with the turbo silencer?

pull the silencer and plug it, i used a mobile one oil 4 litre jug cap, rtv'd it in and a couple of zip ties for good measure. and ya three inch down pipe and four inch back straight pipe sounds great. id suggest it.

Well Mine is a 1996, and i have a cold air intake and the only piece of plastic coming out of it is the line for the egr, and the filter change gauge. What do they look like on the newer trucks?

its the plastic tube coming off the front of the stock rubber intake tube. if you have a cold air its no on any more
