With the larger cells and fast exhaust flow rate, it is smooth, durable and does not have refractory wool burn-out problems. The higher the number of the cells, the smaller and denser the hole is. The higher the back pressure, the more it can enhance torque performance, while the opposite is true for increasing horsepower. Converting your stock catalyst converter (400~800 CPSI) into our metallic catalyst converters will result in significant enhancements in airflow discharge that circumvents the limitations and parameters set by car manufacturers.

Great shirts.
Size: X-Large, Color: Black
I have 10. These are great, stylish shirts especially for the price. I usually wear between size L-XL slim fit (Banana Republic). I’m 6’ 200 lbs medium athletic build and L fits perfectly. With a quick press, they do not wrinkle easily. I get plenty of compliments.

Runs large, not slim fit
Size: Medium, Color: Green
The shirt definitely runs large like all the other reviews say. I usually wear a large, but the medium fit much better. The shirt is definitely not slim fit though.

Great fit and look
Size: Medium, Color: Grey
Husband loved it! Great fit and he said it was comfortable. Can be worn untucked or tucked in pants. He wore it with jeans and a blazer untucked for a graduation party and looked perfect for the occasion.

Tight in Chest for Broad Chested Men
Size: XX-Large, Color: Green
Quality is okay but not great. The biggest problem was the size. It was too tight for my broad chest. Ended up giving it away. I bought some similar shirts from a different supplier that I didn’t have issues with.
