## Questions & Answers

**Q: How would this sound if you made it a dump exhaust with just a short section of pipe?**
A: I have dual turndowns before the rear end on a 2008 5.3 silverado and I think it sounds good. It’s a single cab but the drone is not unbearable

**Q: Does it fit mini cooper s 2014?**
A: I don't think a mini cooper has 3 inch diameter exhaust tubing from the factory.  You would be better off looking for an axle back kit or a cat back kit.

**Q: Does this fit a 2017 dodge ram 1500 crewcab ?**
A: It is not a bolt on unit, but will work if taken to a muffler shop. The easiest Bolton. Unit is made by carven and is less then 500 I believe is what I paid for mine

**Q: Will this work on a 2015 Nissan juke**
A: No.  Need something smaller
