## Questions & Answers

**Q: When it says 3 inch diameter, is that inner or outer diameter?**
A: OUTER diameter.

**Q: Can somebody upload a video of this muffler? I cant find a vvide of what it sounds like**
A: Consider it done

**Q: Would this sound good on a gmc 4.3**
A: I have a complete 3" exhaust on my 4.3 with this muffler and it sounds awesome.. idle sounds just like a v8. Very deep sounding. You won't regret buying this!  Also suggest the flowmaster 3" high flow catalytic converter.

**Q: Whats the best way to put tis on if i have a 2.75 exhaust?**
A: I had 3" coming into the muffler and 2.75 leaving, they make a 2.75 x 3" reducer that worked great. I don't see why you can't have the reducers on each side if needed.
