Just wondered what are the best options for a better backbox on my s3. At the moment i have a relentless downpipe and sportscat fitted. Also managed to get hold of a miltek centre section fairly cheap off ebay ready for when i get hold of a backbox. I wouldnt mind a miltek box but they are quite pricey. Are there any other options that will fit my setup for a bit less money maybe that are still good. I not going to get some cheap universal rubbish.
