Question type: Car Customization

I have a 2.5 L V6 2004 Skyline and long time ago I removed the catalytic converters,
replaced straight pipe and added a big bore. It's way too loud for the neighborhood im
moving too... how can i fix the problem?

I am aware that I can added mufflers and silencers but I want an affordable way than replacing the cats again with new ones... just want to get some ideas thats worked for others ?

Have you checked out the complete line of Flowmasters, or even Gibson, you can get some that will quiet it down a lot.
