Any problems putting 3’ exhaust on 70 Dart ?

I didn't go out the back with mine. I cannot STAND duals straight out the back. I did mine at like a 45 degree angle dumped kinda in the front of the portion of the quarter behind the rear tire.

Similar to this.

Boy that pisses people off at the car shows. That's a Chevy thing. Mopar always had their exhaust straight out the back except maybe the TA/AAR.
