05 Tacoma Exhaust question

Hi I'm new to this forum. I have a 05 Double Cab 4.0 4x4. I was reading some posts and it seems just getting a muffler is the way to go over a cat-back. I wanted to find a spare OEM cat back system and hack that up instead of my stock one... My question is will an access cab system fit my double cab?... or can it be easily extended or shortened?... what is a good price?... thanks

 

im assuming an acces cab system would fit. just have to add a little extra pipe one the straight section.
thats just my opinion and what id do. idk about anyone else lol

 

thanks... i've been reading some posts and from what I can find i guess the access cab exhaust is the same as the double cab short bed exhaust... If i'm wrong anyone please let me know
