Engine/pipe distance question
 

I have a RAM 500 in a BVM bypass with a double walled tail pipe. What would you say the correct distance between the end of the tail cone and the begining of the inner pipe?
I had mine at two inches but was told thats too much so I have changed it to just less than one inch but now the engine seem noisy.

thanks
