   but my car all of a sudden no longer pops or bangs, since i have 4 2 1 manifold, de-cat and straight through pipe it popped and banged like no tomorrow, what can cause this to stop?

   using high octane fuel can reduce this happening as the fuel burns better also using good plugs. do you still have the 02 sensors in?

   when its not popping and banging it means your engine is running good, popping and banging is not good for a engine. i wouldn't worry about this if anything a gentle burble when you let off at a high rev is much better

   run the car on cheap cheap fuel and you will get pops due to the poor burn
