Viltor Posted August 30, 2015 Share Posted August 30, 2015 Hello everyone, I have a question, my MB6 has his stock header with a straight exhaust pipe of 60mm external diameter. Im thinking in replacing my header to a Tri Y header 4-2-1 wich has 2.5 ~63.5 external diameter. Do i need to do any modification in the flanges ? Can anyone give me some advices ? thanks Quote Link to comment Share on other sites More sharing options...

If you can find a exhaust clamp that goes from 63,5mm to 60mm that would be perfect, then just join the mani and the rest of the exhaust like this for example: Of course you'd need one with a flange to match the mani, or weld one on.

KiNK43 Posted August 31, 2015 Share Posted August 31, 2015 Would an adjustable decat be the answer? 1 Quote Link to comment Share on other sites More sharing options...

KiNK43 Posted September 8, 2015 Share Posted September 8, 2015 Don't know but i have the same in my watch list. They do other style manifolds aswell and the photos look really good don't they. Quote Link to comment Share on other sites More sharing options...
JK1245 Posted September 22, 2015 Share Posted September 22, 2015 Don't know about their manifolds but the decat I got off them is top quality Quote Link to comment Share on other sites More sharing options...
Jayhoath83 Posted September 23, 2015 Share Posted September 23, 2015 I would say a custom de-cat would be the answer to get it too fit but like me you will then have to get a custom cat too pass emmissions at test time better off getting a full system from powerflow to be frank Quote Link to comment Share on other sites More sharing options...

Thanks Hi, you should not have a problem with the A/C. You should only need a adjustable decat with 2.5" flange , keeping in mind the tri-y manifolds are quite a fair bit longer than your normal manifolds. The runners going down are also longer resulting in the manifold to hang 3-4 cm lower than the sump, just something to take in to consideration if the car is lowered.
