Lo All :D
Anyone on here know what the outside diameter of a standard Lude exhaust is ?
My US system I have fitted at the moment is 2 1/2 inches.
Cheers

Lo :D
Thanks for that.
I have ordered a new back box with a twin 3" style.
It says it's 50mm DIA.
Problem is the US one I have fitted is 2 1/2" so I will have to replace the cat back section won't I ?
That's a pain :roll:
Cheers ;)

Lo All :D
Received My new rear box exhaust today after having to pay more than £70 on top for custom's tax :evil:
It looks great and it does have 2" dia pipework.
Will fitting a 2" tube rear box onto a 2.5" tube centre section cause any issues ? as it being reduced.
Cheers ;)
