The Taylor cable Helix is deffenitly one of a kind product. Installation was as easy as tiing your shoe,and took me only 20 minutes to install in my 2004 silverado. It looks cool and I even get that sweet whistling sound when I hit the gas! There's more power when I need it, and I'm getting more gas mileage too! I would recommend this product to any one who wants more horse power and more gas mileage for a great price! I couldn't ask for a better experience then the one I had with autoanything.com. Thank you so much and looking forward to all the other great products you have!

Installation was very easy taking only a short time. I primarily use this vehicle for towing my travel trailer and will be taking a trip this coming weekend. Pulling it over one of the mountain passes here in Washington State should give me an indication of whether or not it has been a worthy investment. As far as the truck goes ('04 2500HD w/ 6.0L) I have added an OEM replacement K&N air filter, a Flowmaster 70 series muffler and a Diablo Programer. The only other upgrade I am considering is a cold air intake system.
