Exhaust Upgrade!!
I own a 02 3.0d sport and want to upgrade the exhaust to look like the 4.8. Don't know what makes are the best fit or if it's worth having a custom one made. I know people have tried different options but no real overall answers about the best result. Any advise please?

If u upgrade the exhaust to something similiar to a 4.4i or anything that has the exhaust tip point horizontally out you will lose back pressure on the turbo and you will suffer greater turbo lag.
Theres a reason why the oem exhaust tip doesn't simply exit straight and down but curves back on itself. If you insist on doing it let me know the results.

A very simple and inexpensive mod is to cut the existing exhaust tips and weld on a pair of aftermarket oval exhaust tips like these two tips from Magnaflow and Ractive:
  Here are some links to pix and discussion of tip installations: http://www.xoutpost.com/x5-e53-forum/...installed.html http://www.xoutpost.com/x5-e53-forum/...ed-w-pics.html Expect to pay around $50 per tip + installation. Last edited by asawadude; 02-03-2007 at 03:34 AM.

The magnaflow probably have the right length, but would be a bit narrow for the opening. The wider ractive tip still won't be as wide as the 4.6/4.8, and it may be a bit too long for the application, but that can be easily taken care of.

A muffler shop quoted me $120 to $150 to remove my stock tips and replace them with these.
