Cinnamon 75 Duster \

where is it coming from you did a stock exhaust right?
Yes stock exhaust. Not brand new, so I am wondering if that's my problem. Especially the cat. I have the pipes from Mitch. That would get the cat out of there. Those are slightly different. Think they are correct for 111" cars, (Duster 108). And the muffler is a few inches longer as well. Looks like that would be too close to the axle.
