I almost forgot how fun of an add on these SRI's are, after an easy 30 minute install following the provided instructions the SRI was in and ready to go. First thing I noticed was the sound it gave my 4 cylinder engine, it sounds great now anything over 3000 rpm has a very sporty/deep tone. As usual with these types of products one could expect slightly faster throttle response, Improved gas mileage and a great sound. I Highly recommend this Product!
