Cut off the cat and put straight pipe or resonator same diameter as all exhaust?
Catalytic Replacement
Hello Community!
I´m new on this Forum and wan´t to give you a short summary of my self before I state my question:
Name: Thomas
Age: 22
Country: Austria (Europe) - Sry for my bad english
Car: Celica T23 Wittmann Edition (GT with 6 Speed 143hp)
My Question:
I want to replace my catalytic converter with a straight pipe (I know it´s illegal!). But it seems that I have to craft a special pipe for that. Catalytic input diameter pipe is stock 70mm (~2.75 inch) and the output diameter is 55mm (~ 2.16 inch). I suggest to use a pipe like this:

I don´t now all the diameters for sure (only from a german celica forum)! :/:
I realy want to know which pipes you used for your catalytic replacement - this will be a big help :smoke:
Thank you and best regards,
Thomas
