I know alot of you don`t like this,but here it goes I have a 350 Chev in my 69 Bird with 2" pipe from the headers back into 2 Red Devils or chambered Red Bullets if you want to call them,with tail pipes bent over the axle and exit just under the lower Q-panel,near the rear spring shackle,when you are driving they have a nice rumble and when you get into the throttle they have a nice rap to them.
