Need Help On Exhaust Pipe Sizes
We have been asked by many customers to provide inexpensive and easy to use “couplers” or “adaptors” to facilitate the use of our 3” Street /Strip cutout into F-Body environments without the aid of exhaust shops or welding by the consumer. This will be a part that will allow installation of the cutout by means of “band clamps” . The part would fit over our 3” OD cutout and over the existing F-Body exhaust pipe aft of the Y pipe and forward of the “split” to the muffler. The question is: EXACTALY what is the outside diameter of an F-Body stock exhaust pipe in that location and did the size of this pipe change over the last 10 years? Naturally, we will provide “couplers” for non-stock applications such as 3” and 4” systems. Please reply with any suggestions you may have –Thanks!
