Only issue which was pretty significant one was installation. Ordered for my model & engine but came same diameter as the CAT pipe bolting to. Had to get a reducer. Little louder than expected at low RPM's but love it under hard acceleration. Noticeable difference in HP and even get 3-4 more mpg (also added K&N intake kit. Overall LOVE IT.

At an idle my stock L6 sounds Awesome! Under hard acceleration, ( peddle to metal ) it leaves a wee bit to be desired, meaning, A little loud for my 70 year old ear. But when she reaches cruising speed a smile of contentment brightens my face once again! Hey everyone, She Purrs like a Dragon and when punched, She Breaths Fire!

The sound is intoxicating

The appearance of this exhaust was almost too nice to stick on the bottom of a vehicle. The installation was a bit painful. The stock clamps and exhaust were a royal pain in the a@@ to get off. I wound up having to cut the exhaust about a foot forward of the muffler and getting some 2.5" tubing from auto store and making it work. Wife loves the sound and the pick up is amazing. The deal I got on this feels like robbery. Thanks!
