J;s diffuser WILL NOT fit with the stock exhaust...THIS IS A FACT! i tried it this weekend 
Just a little trimming and you should be fine.....it's not rocket science.

That's funny.....I have had one for six months now with a stock exhaust and it fit fine!!!

So let me ask you a question...how the hell did you fit the bracket to mount the diffuser when the back of the canisters for the AP1 exhaust the loop piping? get in the way of the bracket hence you cant mount it with a stock AP1 exhaust

I modified mine. I know its not the stock exhaust, but my piping blocked the U brace from fitting. I had to cut a section out and than reinforce the cut part just in case it gave.

here is another problem i have heard with the j's racing diffuser if you ever decide to go aftermarket exhaust:
you will have to cut off one of the hangers to clear the mounting points for the diffuser if you ever got with getting an amuse r1-titan exhaust
and as for what ajpwr said i have heard you did not have to do any trimming and it should fit
