I have a Loudmouth on my car right now and this weekend I am getting a 3 inch y-pipe made and I will also have no cats. I have a OBd2 car but I should have my OBd1 PCM in any day. My question is how much power to the wheels will I see with the y-pipe, no cats, and Custom OBD1 PCMforless program.
Also everyone knows that the Loudmouth is already pretty loud and when I have no cats its going to be very loud so how much would a muffler and what muffler should I use to go in the place of the Resonator to tone down the sound some.
Does any have any type of sound clips.

 

most use dynomax bullet race mufflers on them,in fact thats what i have on my duals,still loud but good tone.bout 35$ each,summit,jegs,etc.
