Bought this for my wife. She loves the deep raspy tone compared to the stock exhaust.

LOVE THIS EXHAUST. SUPER EASY INSTALL. LOOKS GREAT, SOUNDS GREAT. NO IT WILL NOT MAKE THE V6 SOUND ANYTHING LIKE A V8 TO THE TRAINED EAR BUT IT SOUNDS SUPURB FOR A V6. BEST MONEY YOU CAN SPEND FOR A BOLT ON EXHAUST FOR THESE CARS. MIDDLE OF THE PRICE RANGE BUT TOP NOTCH QUALITY COMING FROM THESE PIPES..... THANKS AGAIN ROUSH FOR ANOTHER GREAT PRODUCT AND THANK YOU SUMMIT FOR ANOTHER GREAT SERVICE ...read more

Best money I have spent!
