ARH NPP mufflers

I just bought a set of Hurst branded Flowmaster NPP mufflers to go with my ARH long system so ARH should be coming out with a set of their own NPP mufflers any day now

ill take some pics of the logo tomorrow after install. dont want to take the foam off the tips until there on the car. Unfortunately the the ARH pipe is 3" and the 2.75" factory muffler goes in side it. On these mufflers they are 3" and suppose to go over the factory 2.75" pipe. So both pipes are 3" so ill have to get the ARH pipe stretched to go over the mufflers.

well to fit it to the ARH pipes it had to be welded on an the muffler pipe needed to be cut. because of the hangers the tips sit to far in to see the Hurst on the tips and i didnt take pics befor they were put on because they were wrapped in foam. They are louder then the stock NPP with the valves closed but not bad. Valves open is about the same as strait pipes. IT LOUD. but no bad drone. no annoying drone at cruise. In stealth mode the valved rattle quite a bit under moderate throttle were the valves would normally open but they dont at cruise or when open. over all im happy with it.
