like it says who put a 5'' straight pipe on their OBS truck. did you have a local shop do it or buy a kit from somewhere. Also how much did it set you back. any help would be good.

I've never seen a 5" straight pipe on an OBS but I had a 4" straight pipe on mine before I put my stacks on. I just had a local muffler shop do it.

I put mine in from a kit from Tymar. Can't remember how much it cost, but it was pretty reasonable. Mine uses a 5" free-flowing muffler. It took a little bit of fabrication, since my downpipe exits at 4" dia. Dale at Tymar went ahead and welded on a 4" to 5" adapter for me on the downpipe. It's pretty snug where it passes over the axle and past the spare, but it does fit.

Regards,

i went to a Keller Truck Parts today to buy pieces to make my 5" dual exhaust, and that is the way to go. much cheaper then a kit, just as easy to install if you have a little mechanical skills and common sense.

Yeah, pre-rear wheel is sorta easy, its just gettin up over the axle thats the trouble. Just go somewhere they sell 4" and up exhaust (truck shop) and you can find pretty much all the pieces you need.
