Better than I expected
Nice deep throaty sound on start up, & just the right amount of rumble when you get on it, but not too much (didn't want it to sound like a muscle car, it's a daily driver). I was impressed at how it doesn't drone on the highway and I can still have a conversation with my girl as we drive. Definitly gave it some more umph and will turn heads when I get in it hard! Picked up about 1mpg, when I can drive it with stepping off in it deep(love the sound).
2014 Grand Cherokee 3.0L ECO-DIESEL
Easy install, 90 min. Hardest part was removal of stock exhaust. Absolutely no difference in sound, could even be quieter than stock, but definite improvement in engine operation. Smoother operation, during acceleration thru the gears. Added a K&N intake system and it is a totally different running vehicle. Wanted to try these before adding a Bullet tuner. I think I will wait to see how it pulls a 26' travel trailer before adding the tuner. Great value.
