ATS system - Diesel Forum

Is the ATS complete system loud? If you take the muffler off does it have that rap when you let off like it does with the stock downpipe? Will using a downpipe-back 4" off a powerstroke make a bigger difference when it comes to sound rather than the ATS 3"?

no, its actually decent. bigger downpipe will make a big difference.

Decent meaning decent sounding, or decently loud? We're going for a loud good sounding diesel, weather it can be done with this motor is what im not sure of.

Another question. Does anybody have the complete turbo upgrade with turbine housing, etc? Larger gains over just the outlet housing and downpipe? Thanks guys, just curious, I like to know what im gaining before i buy anything.

The turbine housing is suppose to help with the turbo lag, not sure if it worth the $$. But the out let and down pipe is the best mod you can do (along with a modded inlet).
