Which muffler would you put on a 400hp 351w. I have already installed full length headers. I not going to run the pipes all the way back, turning them down right out of the muffler. Need something not restricted, something that will let the exhaust flow freely.

Thanks, Mike

 

any type of performance muffler would work well. for the most flow i would go with glasspacks, but if you want a really nice tone i would just get 3" inlet/outlet flowmaster 40s.

 

I SO AGREE WITH JOJO-3838,CAUSE I JUST PUT MY FLOWYS ORIGINAL 40'S AND BOY THY'ER LOUD AND SOUND SO COOL.U GET DIFFERENT TONES ACCORDING TO THE PRESS ON THE PEDDLE.MY OL LADY WANTS TO TAKE THE TRUCK TO WORK NOWA DAYS.
