Difference between H and L model downpipes

[Adamzxr4]

As this question is asked a lot on here just thought I would post this l model downpipes fit H models fine the only difference is the positioning of the bolt holes on the flange where the can bolts on, a round bolt on can would still fit fine but if you fit an oval off a H model onto L downpipes it won't fit properly as the angle of the holes make the top sit out too far just thought I would post this as it was a problem I had cheers Adam
