Do a bit of research before you buy it. I've heard they are not very good. And that they don't pull very well in 6th. Standard gutted is best followed by the dep. i just sold my standard spanny to syphillis. And there are loads on the web. So if you just want a black one they're you best bet.

got a standard gutted, but it has been welded up around neck- inside you can see lot of weld penetrating- which i figure would affect gas flow etc? not had good enough run on bike to determine if its gonna cause problems.

had a fresco pipe many years ago...was decent enough- also had DEP when they first come out-called it a power advantage pipe back in the day lol...found that it caused power to be further up rev range

 It would affect the gas flow  aye, but not sure whether it would be an advantage or disadvantage, when it came to welding any gas or oil pipes, we'd have to 'purge' the inside of the pipe with an inert gas usually Argon, so as not to leave a prominent root inside the pipe, as having a prominent root inside, makes it have a 'rifling' affect, meaning that as the gas or oil hitting the roots making it spiral and accelerate the flow inside the pipe. So any exhaust gases inside the exhaust hitting a prominent root, and accelerating out faster may be a good thing?

Dep isnt that much. Only £180. Can pick a used one up for £60. And spray it black for £10. Thats what seany's done. Looks alright too!
