Great exhaust system for the money

"I love the sound of flowmasters. Some people say that they droan but I can't say I agree. With a properly sound deadened car, the interior noise is minimal. Make sure you use the rubber isolators or you will experience the dreaded interior droan. Overall it was an easy install and the system looks great. You can't beat the system for the money."

"Really like the looks, and price was very well below other places I researched. Improved performance of my Z28. I got rid of clamps that were hard to get exhaust tight enough to my liking. Sound is great! Little bit of a tight fit going to the three inch system. I highly recommend getting it welded, which I did. Even sounds better. Over all, I am very satified and recommend this product. received the system in two days. Thank you Autoanything, I refer your company to every one I know."

"The sound quality is impressive to say the least and it looks great. I have only had it on for about a week so I'm not sure about the improved efficiency or horse power."

"I love the exhaust system it makes that nice quality flowmaster sound without being too loud. Perfect exhaust for the everyday driver who doesn't want that loud deafening noise everytime they lay on the gas. Only one bad thing is they didn't supply a new clamp for where the old and new exhaust mount together. I ended up just welding where they meet, as well as welding the rest. Awesome Flow!"

"Easy installation, quiet at idle, but when you step on it , it sounds mean without being obnoxious. I recommend it to those who don't want a system that is too loud with a constant humm."
