Hey guys. New to the forums here. I've got a 96 4.0 SOHC sport running stock exhaust minus the muffler and post muff pipe. I like how loud it is, buuuuuut I would like it louder. Can I do a cat delete and get a pair of these http://www.bigdaddiesgarage.com/straight-cel-fix.html?gclid=CLWbvZjK0bgCFejm7AodKg0AnA .I am also wanting to make it true dual, so could I not get the o2 sims since I would be reducing the air flow to the sensor, which is what the sims do anyway.
