Dynomax Ultra Welded exhust for my 2012 Tacoma TRD DC and Long Box

I'm thinking about ordering a Dynomax Ultra Welded exhust (part number 39447) for my 2012 Tacoma TRD Sport Double cab and Long Box. However, the website i want to order it from says it only fits a Double cab with a short (5 ft) box. I believe this is incorrect, in that it actually comes to fit a DC with a LB and it needs to be cut down to fit a short box? Does anyone know if this is correct? Just want to make sure before i order it only to find out its too short.

Thanks

Of course, it's a 440 (7.2L engine) with a slight cam, but it was Dynomax Ultra Flows.

 

Nice 70 road runner! it sounds great!

 

thanks
