"I was looking for a muffler that had a nice beefy, rumble to it without being too loud while driving. This set up is quiet at low rpm's but lets you know its there when you step on it..with no drone. Great product."

"Inside at highway speed - a very low, barely noticeable hum. During normal acceleration - a comforting rumble. Punch it - you know it's there. Does seam to increase performance and m.p.g.. Flowmaster plus the K&N intake I put in earlier, together, make a solid performance increase and my Tundra soundslike the good old days and my 68 Barracuda S. I had my local shop weld the exhaust pipe joints. - Sarge"

"Relatively easy installation - spent most of time getting stock system off (2005 GT). The look was even better than I expected (the black mufflers hide quite well - so you mostly notice the large polished tips). Definitely louder than stock at idle - also very nice burbling when off of the gas (I just love that!). Only moderately more aggressive than stock on WOT, but based on other reviews I was expecting that. Overall very satisfied - especially at this price."

"I installed this system on a 2010 Ram 2500. They didn't have one available for it but the one for an 08 fit just fine. I had no issues at all, everything went on great. Would have been helpful to have an extra set of hands. Jack stands work but not the same as having another person help hold/turn things where you want them. Havn't noticed any gain in mpg, but they system sounds good and I'm sure it has helped some. For those that say the old exhuast is hard to get off..........just split it with a grinder or cut off wheel and it will slide right off. My neighbor has an 08 ram 2500 and is getting ready to order on of these and have me put it on for him. I've gotten alot of complements on the sound since I installed the system. Great stuff."

"This exhaust was installed on a 06 Nissan Titan. The exhaust kit was extremely easy to install and the instructions were dead on. The sound was exactly what we were looking for...not too loud but deep and "throaty"."

"This product is just right if you want some added sound, but not too much sound. It also gave my truck a little extra power which is what I love about it. I would have to give this product a 8 out of 10."

"I installed an AEM air intake & Flowmaster exhaust on my 04 Chevy silverado. Both are easy to install and really add performance. Autoanything was super helpful and I would recommend them to anyone who needs anything auto. Ill be ordering more great items from you guys, no doubt. I also installed a billet grill from Putco & a bull bar from Westin. Great products,great prices,& even better customer service. Thanks for every thing-RJD"

"This system has a lot of exhaust drone on a 2010 Mustang GT convertible with the automatic transmission. Sounds good when you get on it, but otherwise is a bit loud. Probably would be better with a manual transmission, as you are able to avoid the lockup torque converter. It is a good value for the money, however."
