Proudly introducing the CAT 3406E Sound & Engine Pack. All sounds were professionally recorded from Kenworth W9 which has 5-inch straight pipes and the all-time classic 550HP CAT 3406E engine! 

• Full engine sound set professionally recorded from the engine, intakes and exhausts including a multi-stage jake brake.
• Complete engine RPM spectrum recorded, producing a very detailed sound.
• 455HP, 475HP, 550HP and 669HP (tuned) engines included.
• Will work with all default trucks and popular modded trucks such as the Rollin 389, Jon-Ruda W900 etc (see full list).
• Open Definition files for modders.
• NEW and IMPROVED Zeemods dynamic volume system (means the volume of the engine exhaust, turbo, intakes etc will fade more realistically, see product image for more information).
• Zeemods dynamic exhaust system (means that distortion, reverb, phasing and exhaust chugging effects are dynamically applied to the exhaust sounds depending on the engine strain).
• Zeemods multi-stage jake brake (includes all 3 jake brake stage sounds with special intro/outro).
• Includes a FREE bonus - Zeemod Air Fresheners!
