## Questions & Answers

**Q: Will this fit a 2010 ford fusion sel?**
A: If you take it to a good exhaust shop they can make it fit up pretty well, that is what i had done.

**Q: Will it fit Hyundai Santa Cruz?**
A: The Borla 40659 Universal Turbo Center/Offset Muffler is a universal muffler, which means that it can fit a variety of vehicles. However, it is not specifically designed to fit the Hyundai Santa Cruz.

The inlet and outlet diameters of the muffler are 2.5 inches, which is the same as the factory exhaust system on the Hyundai Santa Cruz. However, the muffler is 14 inches long, which is slightly longer than the factory muffler. This means that the Borla muffler may not fit perfectly in the space provided for the factory muffler.

In addition, the Borla muffler has a different sound than the factory muffler. The Borla muffler is designed to produce a louder, more aggressive sound. If you are looking for a muffler that will give your Hyundai Santa Cruz a louder sound, then the Borla 40659 Universal Turbo Center/Offset Muffler may be a good option for you. However, if you are looking for a muffler that will fit perfectly and produce the same sound as the factory muffler, then you may want to consider a different option.

**Q: are these quiet-ish? Dont wanna go around rumbling.**
A: mine is on a 4.7 tundra . I don't have dual exhaust just replaced my factory muffler with this one. it is a strait through design like a large diameter glass pack. It is louder than stock but not as loud as a Flowmaster series 40. My wife said it is more of a deep sound rather than a loud sound. Hope this helps

**Q: Will this fit a 1974 chevy impala?**
A: They are completely universal, I would double check your existing muffler dimensions and Inlet/outlet offset to make sure it would line up with your existing piping if you don't plan to replace the midpipes/tailpipes. Hope this helps
