Hey guys,

Does any one know where I might be able to find a 5" downpipe with the HX40 style inlet?

Thanks.
 
i asked rip at source automotive since they make one for their twin setup but they told me one won't fit running a single.
 
you can build one that will fit, but it would be a little tight to just build off a jig and expect it to fit every truck out there. I built one for my '97. it was 4" through the first 45* elbow and then 5" from there out.

There really isn't any performance gain to it... probably better off just going 4" to the 2nd bend (regular ol' 4" downpipe) and then go 5" once it straightens out under the truck
 
I'd imagine that it wouldn't fit between the trans and frame. Even a 4" pipe doesn't leave much room. I have maybe 1/2" on each side.
