What this mod does

Mack MP8 Straight pipe sound is a sound mod by SlavJerry for American Truck Simulator. It recreates the 415 to 445 hp Mack MP8 engine with a straight pipe. It has over 42,000 subscribers on Steam Workshop.

Compatible trucks

  • SCS Mack Anthem and Mack Pinnacle.
  • Mack Superliner by KSW.
  • Mack Pinnacle CHU613 by galimim and Redd.

What’s included

  • Variable geometry turbo with realistic behavior: it spools up during the first 15 seconds of a cold start, meaning the first time you start the truck after launching the game.
  • Distance attenuation and distortion based on your position around the truck.

The samples and engine specs are by SCS Software; SlavJerry did the sampling, mixing and mastering.

Version

The page doesn’t state a game version. The latest update is from October 8, 2024. Several users are asking for a version with a stock exhaust, which the page doesn’t offer. It’s about 1.6 MB.

Tip

If you use several sounds for the MP8, keep only one enabled. If you can’t hear the engine, analyze your game.log with Holyfix.
