## Questions & Answers

**Q: Is this muffler quieter or louder than a flowmaster super 44 delta flow? And in what way?**
A: I would say quieter. It doesn’t have that typical open chambered flowmaster exhaust tune (not that that’s bad in any way lol). It’s a little more mellow under light acceleration, but sounds great wot!

**Q: Whays the difference between this one and the 12288 model**
A: The 12138 has a 14” body length and 20” overall length. The 12288 has a 18” body length and 24” overall length.

Great muffler. Flows nicely and deepens the exhaust note while removing the rasp. Definitely recommend this muffler.
