ive got a japspeed downpipe & its so bloody tight to get on its unreal & just fowls the studs everytime its fitted or removed what would be the best way to make these slightly bigger?

 

i had the exact same problem and only way i could get it on was to drill the holes out a couple of mm 's.being stainless steel though its not to easy to drill so take it steady and in small graduations

 

Cheers mate I shall give it a try with a drill & see how I go on can't be no worse than it is already wish I'd not bin so tight & got a better one but live & learn

 

dont no why they sell them with so small holes i sent my first one back cause i could nt get it on.Then was horrified to find the second was the same and just could nt be bothred to send it back.cant quite remember exactly but i think i drilled holes out to either 12 or 13 mm and it fitted like a glove
