"The muffler was shipped promptly. It does give my 3.7l Dakota a beefier sound but not as loud as some say it is... maybe that just because I only installed the muffler and tip without pipes or anything. All in all a great buy."

"I hooked up a single 3" in, duel 2.5" out muffler with 3 inch chrome tips and it sounds greater than I ever imagined. I've started a new trend at college. I've heard them on the internet, but since I have them on my truck, i still can't get over the deep throaty sound! When I leave, people know it! Now that the system is broken in the tone is just immense! I have gotten better gas milage and acceleration too! I only use and 1/8 of a tank to go 50-60 miles to school now, instead of a 1/4 tank. And I have a 2003 silverado 1500 with a 327 vortec. The interior sound is a little lound when shifting from 1st to 2nd but after that you just her a rumble. There is a drone at 65 mph and on, but not too bad. Again, I can't say enough about my flows!"

"i put this muffler on my 04 f150 4.6, sounds great. Gets fairly loud. I suggest letting some one drive your ride while you watch so you can really give the exhaust a rating."
