Hello everyone. I'm new to the forum having just purchased. 2006 CTTS. I've also found a Tubi exhaust and have some questions about it before I install.

The Tubi muffler inlet pipe diameter looks a bit small to me so I measured the Inner diameter with a caliper. It measures 2.35 ID on the inlet pipes while the outlets measure 2.60. So I'm led to believe it's designed to slip a 2.25 pipe in the inlet. The guy told me it's for a Turbo. It did not come with any connector pipes so I will need to have those made up.

Now the problem....my 2006 Turbo S has 2.5 exhaust diameter all the way back to the muffler. If I cut it just under the diff do I put a reducer pipe in to connect the Tubi?

Before I do any installation I'd like to verify that I've got the correct exhaust for my Turbo. Can anyone confirm these diameters for me? I'm hoping that I have the correct muffler for the Turbo.

Thanks for your help.

 

Here's a picture of the Tubi for reference.

 

I'd contact Tubi Style directly: (800) 775-2456. My TechArt exhaust came with adapters so Tubi Style will likely have something similar.

 

Thanks for your response. I called and spoke to Victor at TubistyleNA today. I explained what I had outlined above in post 1. He advised that he didn't have the technical information so he couldn't be sure. However he did verify that the Cayenne Turbo and the Cayenne non-Turbo used a different diameter inlet pipe. Problem is that he couldn't verify exactly what the diameters should be so I'm stuck at the same place.

I do suspect that the Tubi that I have may be the non-Turbo version, however I'm hoping that someone that has one can verify their diameters.

Anyone here with a Tubi and can verify inlet pipe diameter?

Thanks

 

I have the tubi for my turbo S the diameter is the same as yours (2.5") and the muffler had the same size connector pipes coming out of the muffler which I welded to the original exhaust they were identical in diameter. This leaves me to believe the exhaust you received is for a non turbo model. Hope this helps

 

Thanks. This is the info I needed to confirm it. It must be the non turbo version.
I think I will sell this one and look around for another.

Thanks again for the help everyone.
