Hey guys,

I had a question about this exhaust. I know you can't change up the xyz on the tdx2 like you could with the v1, but can you change out the mid pipe portion that branches off from the resonator part of the xyz pipe? I heard that the factory one will come as a straight pipe, but can order an hfc mid pipe for an extra 200. Anyone running tdx2 care to enlighten me? What setup are you running? Im wondering how much quieter the hfc mid pipes are and if they affect sound/performance in a big way. Kinda worried the regular straight mid pipe might be too loud, thanks

 

Would also like to know this! Theres a guy on my350z who has that done to his TDX2
