I had an HST rear bumper fitting to my MY55 supercharged. I ordered some HST tips, checking with the supplier that they would fit before ordering. The confirmed they would.

However, they don't as the supercharged has a oval chrome tail pipe end which the inner of these tips do not fit into.

Before I return the items, has anyone got any experience of getting these to fit? Range Rover Sport SVR - Santorini Black

When fitting my AB tips I had to cut of the existing oval tips ( supercharged ) & then weld the new tips to the remaining exhaust pipes. I know it's not HST but I'm sure the supercharged are all 1 part until after the rear silencer box. It's recommended to weld them anyway but it makes the upgrade a little harder - remember to look at existing HST set ups to judge the distance if any the tips protrude from the bumper line - it's all in the preparation or buy the complete set up about £500 in all which gives new rear silencer & tips etc.
Hope this helps  16MY Estoril Blue SVR.............
