Product description

The USP Motorsports high flow cat pipe bolts directly to the OEM naturally aspirated headers and features new downpipes. This pipe increases torque and horsepower through the mid and high range of the powerband by eliminating the very restrictive factory pipe which holds the catalytic converters.

- Gains up to 21 hp and 19 ft/lbs of torque at the wheels throughout the RPM range

- High quality stainless steel, mandrel bent
- Twin 2" pipes merged into single 2.5" pipe
- Smooth transition of twin pipes for free flowing exhaust pulses
- Replaces factory catalytic converters with high flow converters
- 10lbs. Lighter than factory

The fit and quality is excellent.I had not problem with the fit and the clearance was perfect. I was very happy with the hole kit very straightforward in installation. Would recommend to any enthusiast looking for a upgrade from stock.

Advantages: You can feel the performance difference mid and upper rpm pulls very hard. Really complements the flash I have done to the car and adds a little more to the exhaust sound without being ugly.

Disadvantages: Only one I can think of is it’s sold as track use.
