I completed my patriot auger baffle project. I think the car sounds much much better. It has more of a muscle car tone and volume, as opposed to a dragster. It is still loud, but not as loud. It no longer has the harsh bark that frightened me every time I stepped on the gas. The most difficult part of the project was cutting the auger blades down to size. The diameter of each new blade was 3", and had to be cut to about 2" so it would slip inside the side pipe. I first used metal cutting shears, to cut off roughly 1/2 inch from from the radius of the blades. I then finished up the fitting on the bench grinder. I wrapped fiberglass fabric around the inserts, between the blades, for extra measure. I welded a 3/8"coupler perpendicular to one end of each insert, so I can bolt the insert into the sidepipes at the tailend. I cut the end of the sidepipe off, halfway between the end of the turnout end and the main body of sidepipe, so the baffle can slip straight into the sidepipe. I used a 3" band clamp to attach the turnout to the side pipe. I installed the turnouts pointing at about a 45 degree angle down and out. Overall, I am very happy with the new sound of the car. The project cost less than $50.
