Sonnyboyzz- Thanks for clearing up the issue.

I contacted the dealership. They are the 4.6/4.8 tips. I have a few questions which they weren't able to answer... hopefully you guys can provide the help.

1) Do I need to order anything else to install this on my 2001 3.0i?
2) How is the installation? Is it welded or bolted? How much will installation cost?
3) Are the tips purely cosmetic? If i want better air flow and sound, will I need the entire exhaust?

Thanks guys. Sorry if any of these questions are repetitive....

Can anyone help with the above questions?:(

If you read through the first page of this post, you will find your answers. And these tips are just the cosmetic TIPS, nothing to do with performance.
