Extremely Happy with result. Car sound much more sporty and turbo blowoff makes me feel like a little kid at a race track. Install was smooth, the only problem is getting the rubber fitment around the edges. Damn near popped a blood vessel trying to finesse it with the shape of the metal. Overall, It is an amazing purchase just don’t have soft hands like me.
Product delivered early, very pleased with ny purchase.
I have had this product before on another vehicle, its why I have returned.
