Can I do this with the exhaust?

[6.5SmokeStack]

Ok so I have Smoke stacks on my truck.. And I was wondering if i ordered the 3"down pipe from SSDiesel Supply and could I order from them all the 4" exhaust parts to stop at the start of my bed under the Regular Cab?

I have a one stack setup but I got my downpipe from Jardine and I asked if I could get all the parts to get to the front of the bed I also have a reg. cab very easy to do. Its alittle tricky if you just won't one stack but two stacks would be easy as pie
