One of the 2” mandrel bent pipes was cut and welded to form the offset just behind the stock head pipe to align the front half of the system with the muffler. We used the original piece from the stock system as a guide when we made the cuts and tacked it in place. The other one is cut in the center of the “U” and a straight piece was added to match the dimensions of the scallops in the rear panel, this is the piece the Monza tips were welded to. After the entire system was in we marked the legs of the “U” coming out the back using the Monza tips as a guide and then cut the legs back to get the tips to extend back the desired amount.
One of the 2 ¼” or 2 ½” mandrel bent pipes was cut and welded to form the over the axle section. The other one was cut and welded to the over the axle section to tie it into the muffler on one end and the previously fabricated “U” for the section going out the back.
Note: When I did my car I used 2 ½’ pipe over the axle. On OOONER’s car we used 2 ¼” pipe. We used 2 ¼” on OOONER’s car so the exhaust was not as loud and since he has a stock low compression engine we didn’t see this as hampering performance too much.
The muffler is a tight fit being a 4 x 9 oval with an 11” body but it will fit without hanging too low if you cut the stock muffler mounts off.
My recommendation for anyone that wants to replicate this is to get the tips and the muffler and take them and the photos to a good muffler shop and tell them to do it this way, unless of course you like to fabricate stuff. The reason I initially did my car the way I did was because every shop I took the car to run 2 ½” pipe the entire way and only make one tip active. So I decided to do it myself.
