At wide open throttle its going to have more noise of course and any drone is pretty close to stock levels at lower RPM at higher engine load or cruising speeds. We daily drove this car for a few months to test it in all conditions including hwy driving.

The car put down peak TQ gains of 30 ft lbs. with a solid 20-25 ft lbs. gain across majority of the powerband. Horsepower gains were 20-23hp peak and between 12-20 hp gains across most of the powerband. This means great usable power and gains at every RPM.

Hello,

Do you have a dyno for the catless downpipes with the exhaust??

Is this downpipe for sale yet, and what are the prices?
