Read our extended version below.
BRAND: NHP EXHAUST
WARRANTY: LIFETIME AGAINST DEFECTS
Our short tube version are the best choice for daily driver cars because short tubes make more power from low to mid-range RPM's however for track cars and high reving driving our long tube version will be a better choice.
A nicer and deeper exhaust sound will be achieved with the NHP Exhaust Headers, no additional cabin drone will occur with our headers. Better engine response and power that can be felt after your installation.
Hardware and gaskets included.
Important Note Hp/Torque Gains.
After Dyno testing (Dynojet) of these headers on a stock Cayman S (thanks to the help of one of our customers who has done the dynos for us) ,we strongly recommend that you match these headers with a high quality catback exhaust such has the NHP Catback exhaust, if you install the NHP 200 Cell Headers and retain the factory catback exhaust you will still have restriction to deal with from the catalytic converters on your mufflers, therefore by retaining the factory catback exhaust the headers will produce 2 HP and 2 ft/lbs of torque , for these headers to make more HP gains and more torque gains they must be matched with an high flow catback exhaust and you can expect approx 10HP gains.
IMPORTANT MESSAGE ABOUT 200 CELLS CATALYTIC CONVERTERS.
For the State of California our Exhaust Products are not C.A.R.B.
Our Exhaust products have no guarantees about passing emissions in your state.
Our High Performance Exhaust with sports catalytic converters are built and meant for off-road purposes.
Our Exhaust Products “Lifetime Warranty” does not cover catalytic converter error codes.
Please note that when installing High Performance Catalytic Converters there is a possibility that you may get a “Check Engine Light” for Catalytic Converter Inefficiency or other Catalytic Converter related error codes. This may or may not happen, this is due to lowering the Cell Count of the catalytic cartridge, in other words we need to work with the same surface area with a lower cell count, most OEM Catalytic Converters will have 600 to 800 Cells per square inch, High Performance Catalytic Converters are only 200 Cells per square inch. If you get a check engine light it’s not because the product is defective but it’s the ECU picking up the difference and relating those error messages.
There are several ways to deal with this.
Most Efficient is the Flash the ECU with performance software, make sure to tell your tuner that you have 200 Cell Cats. This is the most expensive and most efficient.
Use 02 Bungs, many have been successful by using 02 Bungs however this is not 100% Bullet Proof.
Purchase OBD2 Scanner, read your codes and erase them. For those of you who are not annoyed by the use of a scanner on a weekly basis this is the cheapest solution.
