I just finished putting on a 121 to 136 ice attack track and tunnel extension from Tracks USA. I was just wondering if I had to relocate the rear heat exchanger to the rear end of the extension or will it be ok in the original location?

Just make sure you have 1" of protection on the rear heat exchanger.
I opted to raise my tunnel ext about 3/4" above stock location and use 3/4" extended tunnel protectors.
This thread cover 3 different setups I used. This last I am still using.

On stock LTX or Attak's We found 1 1/2 for rear cooler protection. OEM coolers or add on Attak was mounted at rear most on tunnel. Lot's of theads on this. Some showed less then that the coolers got scraped. Maybe a sticky on this. I used 1.325 Woody's and did well over the 30k miles or so with studs and the protection.
Stock Ripsaw with studs needs 1.5" of protection for the exchanger. The fingers on that track just bend over/break off and allow the 1.325 studs to reach far past the factory protection. With the Ice Attack the paddles are solid and the built in studs don't reach as far thus you don't need excessive protection on the exchanger. But you still need the protection. The link I posted above shows what is needed for both Ripsaw and Ice Attack.
Leaving the extension in the stock location with extended tunnel protectors will cause the track to hit and drag more on the protectors when you bottom out. I have done 2 Attaks with the stock Ripsaw and 1.325 studs where I have raised the tunnel ext and added 1.5" of protection over the exchanger. Also have studded a Ltx leaving the tunnel ext in its stock location and added 1.5" of protection. In both cases the exchangers had been scratched. The raised tunnel sleds had less exchanger scratching.
Regardless if you leave the tunnel ext stock or slightly raised it you will need protectors over the exchanger and the track will still hit the protectors when you bottom out
