Giday all I have cobra swept pipes and wanted to quiet them down a bit I removed the baffles ( what a p$$$k of a job not looking forward to putting them back) anyway got them out and the top one has a hole in a plate I think it's to divert the exhaust gasses through the smaller holes but the bottom one does not have a hole in it is this normal also what do you ppl use to cover the baffles and were to get it. Thanks for any advise.
