50 exhaust on a 70?

I've got a 140 in my 70 and since the head is farther forward the stock exhaust bracket already needs to be relocated. I saw a used Two bros 50 pipe for sale on here and was wondering how much farther would the bracket need to be moved or will I run into more issues with the subframe if I go with a 50 pipe?

Thanks
Josh

Is there a difference between the same company pipe for a 50 or a 70 other than length and/or bend?

Whats the best pipe for performance on a big bore engine?

You have to run a 70 pipe. The bend is deferent and the pipe is a little longer. Two bros and fmf both make a great pipe for that bike.
