## Questions & Answers

**Q: What are the inlet and outlet sizes?  Looking for 3" & 31/2**
A: 3" inlet and 2.5" outlets

**Q: you can make this dual exhaust right?**
A: This muffler will allow you to make a single exhaust system into a dual exhaust system from the rear of the catalytic converter back.It is also a VERY GOOD replacement for factory mufflers in a single in/dual out setup.For instance, this muffler was used in the place of a factory muffler on a 2010 Dodge Ram Hemi - gives fantastic tone without being too loud.

**Q: hello, is that Muffler overall length 24 or 20 inches ? because that number part 12288 description is different on the MagnaFlow website !**
A: Always refer to the manufacturers website for the accurate information about there products. Internet sellers list many thousands of products. Every internet seller makes listing errors with pictures and content. The body of this muffler is 18" and 24" to the tip of the inlet and outlet. Thank you

**Q: What modifications and/or extensions were needed for instalation since muffler is shorter than stock.  And outlets are spaced farther apart???**
A: I have a local dealer Mad Hatter in Fort Lauderdale Florida install dual exhaust after the muffler. They did a fantastic job.
