just going through the price page and they have this along with the hi-flow cat.
BTW, will the hi-flow cat increase noise levels?
would it be better to use it with a catback or axleback exhaust?

 

The high flow catalytic converter does not change the sound of your vehicle.
You really should have the cat installed at a local muffler or performance shop.
The warranty is 5 years or 50,000-mile replacement. They are 50 states legal, as well as EPA and CARB approved.
These flow at least 75 CFM (cubic feet per minute) more than any other catalytic converter, I have found
Only one little problem installing a high flow catalytic converter. Legally the vehicle must be 5 years old or have 50,000 miles on the vehicle. The only way to replace the converter before this time is if the stock converter has been removed or been physically damaged leaving it not covered by the factory warranty.
And anyone thinking about removing there Cat all together, it is illegal and you will NOT increased horsepower
ALL newer vehicle that has a computer and/or O2 sensors it will cause the engine to loose all of its low-end horsepower.

Should give our TL's about 8 HP
I am going to contunie to work with the manufacture, of these cats, on my own TL, to make sure we don't have any problems and that the check engine lights won't come on.
Going to do this first, before I put my name on them.
