"I love the sound it provides along with better performance although my truck is not performance oriented. The engineering by Flowmaster was top notch. Everything fit and was very easy to install. Midas wanted $671 for this system and I got it for less than half. Thanks!!!!!!"

"I was very happy with the customer service at AutoAnything. Very informative and professional. I would definitely buy other products from them. About the system. I think it was made very well. The thing I am slightly disapointed on though, is the loudness level. I wish the system was just a bit louder. I have had people tell me the system sounds stock. I just wish it were louder. Is there an upgrade?"

"GREAT SYSTEM WITH THE PERFECT SOUND. NOT TOO LOUD, JUST THE SOUND I WAS LOOKING FOR. INSTALLATION WAS SIMPLE, BUT THE CLAMPS SUPPLIED, WERE VERY MUCH BELOW MY EXPECTATIONS. GO TO AUTO PARTS STORE & GET SOME REAL CLAMPS BEFORE INSTALLING SYSTEM."

"A monkey could assemble this, it was so easy, no mods or likewise needed. However, the Super 40 Series is a little loud especially when towing a trailer. I'm going to have to tone down the volume by getting a 70 Series muffler."

"when i installed these pipes, i was extremely surprised by the final result. All of the ads and reviews i read boasted loud rumbling mufflers, but these are a long shot away from loud. they have a grumble to them, but i cant say theyre loud. They did increase performance though. The car feels a little quicker and it idles lower so i can save $$ on gas,"
