Any recommendations am I better running arrows,( I presume TEC is same) 2-1 with or without baffles. Ecu has been remapped to suit, and Thruxton is running smooth not even any popping on over run which standard pipes used to do. But when I do use baffles they do seem really sooty. I haven't checked plugs yet. Everything I have seen says in or out doesn't make any difference, anyone know different?
I’ve run mine both ways with no problems, mainly run them in now as I don’t like the noise without. Mine is the TTP tune though as I’ve done other mods
I run TEC 2-1 with the baffle (though it’s a very short one) mechanic said he’d leave it out but the difference in sound (for me) was so little thought might as well just leave it in. Might take it out now and then to see if I feel/notice any difference.
