On my 88 vert I'm getting the RB down pipe and pre-silencer with apex'i N1 duals out back but i am keeping the stock exhaust manifold on. How loud is this going to make my car, and is it going to be easier to backfire now that I have eliminated all the cats on the car ? I would like to know because I also bought the silencers for apex'is just in case it's too loud, but there is nothing wrong with it being TOO loud or spitting flames, thanks

 

It'll be loud...
