I have the modded stock pipes from chevy605. The lead Triumph tech at the dealer in Raleigh NC told me to remove the AI (that will reduce or eliminate the popping) and have it re-mapped by a dealer for 'TORS with AI removed'. He says that will produce optimum performance on the EFI engines.

I'm getting the AI kit Friday, will install it early next week, and hopefully have the re-map done right after that.

Will report back.
