I was wondering would i have any issues in the future if I Placed the JDM header with the STOCK GSR donut Gasket? Also does any know with the BEAKS KIT + ITR sway bar can i still put on a tie BAR? Will it even fit? I thought the collector was bigger. If it fits, and it's not damaged, you shouldn't have any problems.
Different collector size; won't fit. Get a 2.5" donut gasket. I've read that some people have had bad luck finding one that fits perfectly unless it's a factory Honda one. If you want the one from Honda get a S2000 or Legend donut gasket.
as for the tie bar, from what I understand, certain ones fit and certain ones don't, but I'm not sure which ones. If you can put a pic up that shows a close up of the ITR bar mounted by the the Beaks kit, I'll be able to help you more on that.
