This cat-back exhaust system will work with the factory exhaust headers, factory exhaust T-pipe (connecting pipe between both mufflers) and will also work with factory exhaust tip.
NHP Exhaust System with Sound Valves for the 987 Cayman and 987 Boxster. Made entirely of 304 Stainless Steel, welds are works of art , this exhaust will provide you with acoustic pleasures for years to come. Every detail was taught of during conception of this exhaust to please most 987 owner's out there, we believe that the NHP exhaust for the 987 is the most well balanced exhaust out there providing you with a choice of sound with our exclusive sound valve system, with a simple push of a wireless remote you will enjoy 2 different sound levels, with the sound valves off you will get a sports exhaust sound that will only give you a good idea of what's to come with the sound valves on, basically with the sound valves off it's a nice upgrade to the boring factory exhaust system sound, once you hit the button on the remote and open up the valves you can enjoy the real deal a beautiful growly exhaust sound that makes its way out through internal muffler channels that are much less restrictive resulting in additional power, (*The Following comment for Cayman only) see additional notes about cabin drone for 987 Boxster Owner’s “below this paragraph ) the beauty of it is that there is not more cabin drone then the original, this exhaust is so well built with quality materials that will avoid cabin resonance but the exhaust can be heard nice and clear on the outside.
*For Boxster 987 owner’s there is some cabin drone at the typical 2700-3200 RPM Range , after installing a few ourselves we noticed some normal cabin drone levels to be expected in a Convertible, but if you’re a fan of a great sounding exhaust don’t let this scare you, again normal levels that a true sports car enthusiast can live with.
This exhaust features mandrel bend piping, OEM type flanges that can accept OEM exhaust headers or any aftermarket exhaust headers, exhaust supports that are very solid avoiding exhaust vibrations, exclusive sound valves (vacuum activated).
This exhaust weighs a total of 26 pounds (Mufflers only)
This exhaust doesn't require any modifications to be fitted, no holes to drill, nothing to cut.
The exhaust inludes the following:
-Sound valve control kit with FOB remote or Manual On/Off switch
-Left and Right exhaust mufflers
-Left and Right exhaust supports
-Exhaust gaskets + hardware
-NHP Exhaust sticker
This exhaust will need a 200 to 400 miles break in period for optimal sound, in other words after the break in period it will have its natural sound which will be slightly louder than the sound it produces during the first couple hundred miles.
Please review all pictures and videos.
