No air filters, no air box, just aluminium velocity bells, and a GPZ 1100 full standard exhaust system, but I’m looking for a good replacement exhaust or silencer to fit to the bike. cant afford a new Kerker system . So alternative recommendations would be fantastic :D

The Delvic stainless steel 4-1 are good value for money.

I think the downpipes are a little bit small diameter for an 1100R (they're correct for a Z1000J) so you'll get good midrange but won't get as much top end as you would with a Kerker or Vance and Hines, the downpipes are a little bit long as well, which will again boost the mid range at the expense of the top end.

Another good thing about them is that you can access the oil filter without removing everything :D (at least on a J you can !)

And on an 1100R, they look like a copy of the Kerker road pipe that was supplied with US market 1000Rs just with slightly smaller downpipes, you can buy just the front pipes and use a straight pipe for the rest of the exhaust, I've done this with my Kerker, I think the pipe, a baffle and mounting clamp came to under £30, it sounds good, no idea what it'll ride like until April
