So far so good. Have seen an increase in horsepower and sounds great. Did not install myself had mechanic do it. Would recommend to everyone.

Been wanting to put this on for awhile didn't want to spend the 300 dollars so found it on your site with 20% off and free shipping put it at 237 dollars what a deal came a day early in great shape no damage about 45 minutes to install and a extra 13 horsepower and better gas mileage very happy with this purchase and auto anything great company thanks
