Bit busy juggling two bike projects at the min Seany mate, but you sort out the postage back n forth, couple of packets of B&H gold I reckon, but you can polish it mate.
Don't forget i had a stubbied dep that was that long when i first got the bike back dude. wouldn't say there's much of a loss of power if any to be honest, sounds good though :P
And tbh Nev with the end bit pointing down like that i don't think it will resonate adversely as the sound will just be going downwards :)
