Exhaust size

[project_lean]

I need to know the piping size on my 98 with the 2.7. Thank you in advance.

My stock piping that came off my 97 2.7 3rz was 2" and then flared out at the tip to 2.25"

but that has all changed now :becky:

My '97 had 2.25" from the cat back and flared to 2.5". I'm the original owner, so I know it came from the factory that way. :shrug:

If your engine is stock and you plan on keeping it that way, go with 2.25" piping. If you plan on forced induction, do 2.5" or 3".
