4" Stainless Exhaust
G.M. 6.6 Liter Duramax from 2001-2002
The ATS 4” mandrel bent stainless exhaust system is now
available for the new 6.6 liter Duramax diesel. This system lowers exhaust back
pressure to near 0. The system starts at the rear of the engine at the V band
clamp. This stainless exhaust system is made of 409 stainless tubing and
features 304 brushed stainless muffler along with a 5” slash cut radius rolled
polished 304 stainless tip. The tip has a 4” I.D. connection allowing one to
position the tip length one desires and clamp into position. This system lowers
exhaust temperatures as much as 250 degrees and lets one run an increase of
approximately stock exhaust temperatures. The ATS stainless exhaust system comes
complete with hardware, clamps and hangers.
