Down pipe

I don't believe changing the downpipe is worth it, I don't see that much difference in size, just a cleaner flow and it was more of a pain than I thought it would be. only paid $69 for it, just don't see how it could change things much. Glad I had the new V clamp on hand, he tried to reuse the old one but it was leaking.
Thanks for stopping me from doing the up pipes

Its worth doing it on the G4500 just because you can post a how to and ask what the big deal is.

Are you talking about the turbo direct down pipe ? If so it is stupid easy to change when you pull the doghouse. Dyno results have proven the gains are minimal.
If you are talking about the front pipe that did not come with your exhaust then that can be a little difficult due to an ear on the transmission. You either cut that ear off or dimple the front pipe just like the factory did.

The primary benefit of both the down pipe and the larger head pipe is lower egt for a given power/load condition. Like Duane said, the power gain for larger exhaust (unless you made a lot of other power adding changes) will be minimal/none.
