    Hi, I m considering a gear vendor but tti specifically states that it wont fit with their X line
    Has anyone ever managed to get an X shaped exhaust system work with a gear vendor overdrive
    If yes what were the modifications or massaging you did.
    I have a 71 satellite with a tf727 with a 2.5inch X shaped exhaust line

    okay so that means getting smaller muffler too since i would have extend the header to X part right?

    Will that affect the scavenging of exhaust fumes ?

      because i went for X pipes and im from france so the import fee just to get the H pipe to fit a GV overdrive (with the additional import fee for it) would make it really financially painfull
      I never thought i could use a GV so i was happy with the Xpipe but i m starting to use the car much more often and for longer trip so having a lower RPM and better fuel economie could really be usefull

      Why not lengthen the extension pipes, in front of the X-section, and remove what is needed behind it ? You may be able to use the mufflers you already have.

      that s what i m thinking of doing not sure if i can cut from the back to add to the front of the X since the back wont be wide enought to connect to the muffler after that "surgery"
      The other thing that makes me question going for a GV is that i will have to shorten the driveshaft and in france i m not sure we have many people knowledgable enought to do it

      Muffler shop and have H-pipe made that clears the Gearvendor better than the TTI. It's about $10 US in pipe n very little labor.

        just got off the phone with a gear vendor guy he confirmed that a preexisting X pipe will get in the way so i would have to get a metal shop to build me either a compatible X pipe

          Just get a local exhaust shop to fabricate something. When your not in the US (or even if you are) you need to think outside the box a little. I found a local guy here with a CNC machine who has made spacers for my disc brakes, an alternator bracket, some cones for my MTB rear axle all for cheap.
          My car is currently having a new 2.5" exhaust fabricated by a local guy for cheaper than I could buy and ship from the US. I dropped the car off yesterday and it will be ready tomorrow.
          There are skilled local tradesmen all around the world. You just have to reach out and find them.

            No. I used all the original mounting on my 66 but, I moved the engine back as much as I could on my 65, so I fabbed a new crossmember.

            You will most likely have to do some grinding to allow the trans cross member to drop down about 1/4", you may also have to dent the trans tunnel to clear the two ears on the top of the gear venders unit.
