My car is an 03 v6 6speed no intake resonator, k&n drop in filter, and Richie's 2 primary test pipes, the rest of the exhaust is stock, the third cat is still in. The car does not smell any different from stock in case anyone wanted to know, that is usually y i am hesitant to eliminate any catalytics but this worked out great. Thanks Rich for the rapid shipping. The install went smooth and the pipes look professional. The exhaust sounds stock with a little hint of a v6 engine under the hood. Not much of a difference of sound from stock. But you can tell its different. Sounds a little louder in person and going through the gears. I def like the sleeper sound. Oh and sorry for my bird chirping in the vid!
