Well, Recently got my car back from getting rebuilt and he used (Sad for me not knowing) but some offbrand test pipes. Now, When I went down there to take off this tacked up welded exhaust that was made at a little exhaust shop for the time being, The test pipes are too wide for the Y pipe to even fit. Not the flanges but the test pipes itself. I was thinking, Maybe it is my Downpipes? Because I was looking at some High Flow cats and they have a curve to them, My test pipes are just straight as ****.

Any ideas or inputs? Thanks. Leave the negative comments to yourself.

I'll jack it up in the morning to show you guys.

 

Sounds like G35 extensions. I've seen a lot of confusion on craigslist with people trying to sell the extensions as test pipes because they don't know the difference.
