    Hi AM, What exactly is the difference between Pro Chamber and an H-Pipe? Thanks.


    • The difference is that the H-pipe connects the right and left exhaust pipes with a single pipe. The Pro Chamber connects it with an actual chamber that will not only increase the after header sound but will increase the amount of flow to exit.

    Hi can add the Pypes catalytic to this h-pipe for it to be street legal ? Will I need welding or can I just bolt on the cats and this h-pipe ?


    • The Pypes catalytic converters will work with this H-pipe however you will need to make modifications which include welding them in.

    If I get shorty headers and this, could I reuse my cats bolt-on fashion? Or would I need to get custom work done?


    • Hi, This midpipe is designed to be used with MAC Performance long tube headers only, You will need to use MAC Off-Road Pro Chamber Mid Pipe Item# 100662 with shorty headers, and custom exhaust work would be required to use cats with that midpipe.

    Well this work with Borla Long Tube Headers?


    • No sorry, application is specific on the headers,they are made for MAC headers only, I would recommend either getting a borla x/H pipe of go to a muffler shop and have one made

      Had a small problem with the two front pipes that bolt to the headers, but over all love them.
