I was able to get my old Shocker XL to fit behind the front grill of my 09 Cadillac but only with two on each side facing each other at an approx. 30 degree angle. Will they be ok that way and be at their full potential?
Shouldn’t be a problem.
You are right! Got it all hooked up not too long ago and hit about 145psi thru it. Sounds great if not louder than when it was under the rear of my XB! Now I’m going to go tidy up the wires etc. 
Where’s the pics?..
