You have a new system AJP so it'll be okay as long as you keep on top of it where as the previous owners toy golf probably didn't give a hoot about the tips. would like to change them but have to cut the old one off 
True. It was one of the reasons that made me bite the bullet and go for a new system, they just looked untidy and let the car down.
I did consider the A4 tips like those above. But then I asked Nige if he'd do another group buy and the rest is history!
I reckon there's a few options to tidy things up on a budget. The push-on tips being one, and I'm sure it wouldn't be a big job to lop off the rusty ones and weld on some shiny new ones. I'd prefer the cut and weld approach myself, you'd probably be able to get a better fit against the valance.
