What muffler to add in y-pipe to quiet car?
Not looking to change the catback or y-pipe setup. I'm thinking of adding a muffler in the ypipe after the merge but before the rear axle. Which mufflers have people tried? I was about to buy a Moroso Spiral Flow up until I searched and saw someone here lost 30 hp by adding one in the y-pipe (could just be a defective muffler).
you mean weld into the intermediate pipe? No room in the y pipe itself for mufflers. Not any that are big enough to quieten down. The Hooker is already one of the quietest catbacks.
