Very tolerable........muted deep tone. From a stop w/light throttle it rumbles pretty good. As you get to say 40 on up it lightens up considerably. Decelerating ( foot off gas) sounds stock. Coasting to a stop while it's downshifting, you can hear it through each gear as if you have a manual and your downshifting from high revs. Pretty neat sound. The main thing is (like I said a few times) is that the sound stays contained to the back.......there is no drone, all Flowmaster.Sounds good. How is it inside at highway cruise?
I know alot just do straight pipe when deleting the res, but IMO a proper center muffler is crucial when you want to improve or increase the sound coming out the back.i threw a 40 series on one day when i was bored to see what it sounded like and it was extremely loud and not all that cool.
but that was with a 3'' dp and no center resonator
wow! awesome sound at an awesome price!! do you know about how loud it is in db?
