    This oversized 2-1/4 inch dual exhaust system is manufactured right here in the good old USA from original 1968 Cougars equipped with the 289 or 302 engine. This direct replacement system includes: 1 H pipe, 2 intermediate pipes, 2 mufflers, and a right and left tail pipe. The system is constructed from 2-1/4 inch aluminized piping and features blue printed bends with everything being replicated as close as possible to the original. The mufflers in the system have the hanging tabs attached so that they will accept original muffler hangers. H pipes are constructed for use with original stock cast iron exhaust manifolds and H pipes can also be purchased separately. This system will fit 1967 Cougars with 289 engines. 

    *NOTE* This dual exhaust system has a larger diameter than the original Ford system and will increase performance, but it may also increase the engine sound that you hear inside your car. This item ships in sections and is meant to be welded and or clamped together. The H pipes were clamped on the original systems. Kits do not include pipe clamps, hangers, or exhaust manifold donuts. 

    Please allow 4 - 6 weeks for delivery.

    Just to confirm this will bolt directly to the stock exhaust manifold? And, a subjective question: Is the significantly louder than the standard 2" system?

    As stated in the description, it is a direct bolt in replacement, and it will increase engine noise inside the car

    Im having trouble. Do the mufflers need to be cut from the tail pipe to install over rearend. It is one piece welded and wanted to make sure. Thanks

    As delivered, the tail pipe should seperate just after the H-Pipe, you can see the junction in this photo: https://storeimages-westcoastclassic.netdna-ssl.com/dc/8205/1354040793_a.jpg. That junction should only be welded or clamped after the exhaust is installed in the car. With the portion with the mufflers disconected from the h-pipe you should be able to fish the exhaust line over the rear end, then slide the rear section back into the h-pipe once in place.
