I bought a di/do super 40 5 yrs ago and it completely rusted out on me. I bought the same thing again except in SS this time to prevent the rust. I now have dual turn downs instead of dual tail pipes and it is slightly louder and definitely deeper sounding. Since I've been running this muffler for 5 yrs I have noticed an increase in hp and mpg went up by 3-4 both on and off the highway. Easy to install as well took two hrs counting taking the old system off and putting the new one on.

I have the dual in and dual out muffler. It is the best muffler I have ever had. Absolutely no drone and the tone is matched perfectly with the engine! Noticeable gain in horsepower and torque as well as improved mpgs. I recommend this to any one who loves a perfectly balanced exhaust tone. The tone is car show material! This is a better configuration than a single in dual out
