TT I went with 3" from the turbos back so I am catless. If you know of some1 with 3 or 4" tips send the number PLEASE! I almost have my mechanic convinced to give the turbo swap a shot, let's see on Monday when I pick her up.

 

I thought Hank was making a set of tips for you?

 

I have asked twice how that project was coming along and received no reply.

 

Well that sucks. He always seems to respond.

 

He has been great putting the system together and aside from minor fitment issues the exhaust is top quality. It just suck to go 3" from the turbos back banking on the tips and to fall short at the end. I'm trying to source the parts that I need to go from the muffler to 3" tips and I noticed last night that the reducers are welded on so I will be having to cut them off. It doesn't seem like he was planing on making a full 3" system.

 

You did the right thing. Full 3" exhaust from turbos back without cats is the best performing exhaust system for Cayenne TT.

There are couple exhaust companies producing aftermarket exhaust tips in various types with diameters up to 4" or even rectangular or ellipse shaped ones.

I personally like the quality and finish on the Magnaflow exhaust tips. Here is the link for you. http://www.magnaflow.com/02product/02tips.asp

This is the link for the Flowmaster exhaust tips. http://www.flowmastermufflers.com/?p...=Exhaust%20Tip

You will benefit a lot from turbo swap with your new exhaust system. Let me know if there is anything I can help with your monster.
