Special version of SuperQ with added 3.5 inch diameter resonator on the inlet to kill the RASP that is added with adding a standard length highflow header to the ND. Otherwise similar to normal SuperQ, see our standard SuperQ product description for more. STRONGLY recommended for those getting a header!!

Application Notes: Not needed for those getting our Longtube header that has a massive resonator in the midpipe. That midpipe large resonator hangs down a bit under the car, will not be everyone's cup of tea. Thus, for those getting our standard length header, or already using standard length header from another company with our standard length midpipe, this is the cure for raspy sounds unleashed by that standard length performance header. If confused by your choices, give us a call or drop us an email to discuss. Our pipe size is bigger than OEM for best performance/flow and the stock donut gasket sinks a bit deeper into the mouth of our setup than with factory muffler 'mouth'. Note that our flange at entrance to muffler is designed as a dual purpose item that allows going to flat gasket if you later go with our 2.5 inch midpipe, at which point the midpipe has a flex joint to replace function of the donut and you get a clean 2.5 inches of flow all the way, which is not possible if we stay same small pipe of stock muffler.
