aussie-X5,

Thanks for the info. I need to take a closer look at your pics of how you transformed your diesel exhaust system to show the tips without any power loss. I am worried that the bending of the pipes in order for the tips to come out at the hole locations might affect the power of the X5 .

Sorry blueagle we must have our wires crossed. I have replaced the rear end exhaust silencers with a X5 4.4 V8 pair. There is no practical way of putting any sort of tip on a X5 diesel silencer other than fake tips welded onto the silencer wall and that would look crap.

Did you get those tips from this ebay seller?...

These tips on ebay and the ones you had installed are smaller (from what I see in your pics) than the OEM 4.6is tips, but they do simulate the look good enough. Either way, your X does look better. Good job, pare!:thumbup:

These are locally fabricated tips. They patterned it from the original AC SCHNITZER tips. OEM's are more oval than mine .

Sound is more aggressive than the stock exhaust . I noticed a slight gain in power. TOTAL COST : USD450.00 ( parts and labor/installation)
