Factory Muffler Cut / Gut Stealth Modification

Factory Muffler Cut / Gut Stealth Modification

We now offer a stealth muffler mod. This is for those of you who must retain the appearance and sound levels of your factory exhaust. The factory exhaust has a flat sound and poor flow characteristics. The red oxidization in the interior mid bleed pipes proves that there is to much heat because of the restriction. Especially the Sidewinders because they are turbo charged.

This modification is not just cutting the muffler open and emptying it’s contents. We sure up the interior by fully welding the bulk head walls / seams for strength and add directional velocity stacks for a non-restrictive mid chamber full flow. To top it off, the outlets get a directional flowed louvered quiet core that is tuned for the correct back pressure and sound level. Whether stock or fully modified. From mild to wild, just ask Chris if you want something custom. It’s time to release the demons!

By sending us your factory muffler we can provide:
  • SBM designed acoustics to provide a more aggressive and raspier note
  • Directionally flowed quiet core technology
  • Factory appearance and reliability
  • A Savings of 5-8 lbs. and a 4-8 HP gain on average
  • Custom built per customer. No cores, you get your muffler back
