DP ????

Hey guys I'm about to get a single stack in the truck but befor I do should I upgrade the down pipe or just run the stock one?? If so where a good place to get one

I'm pretty sure most of the turbo back kits come with an upgraded DP. Some are 3.5" and some are 4" although I don't know of many running a 4" DP. You just have to read what the kit you're interested in says.

I know I've been looking at running a dual stack set up so that's also what I look for in a kit.

i was just wondering if the dp is worth the money. Or should i just use my stock dp an get the single stack kit i found from a vinder on his site.

Like I said, it just depends on the kit. If it's a turbo back kit, it'll come with one, you just have to look at the description of the kit. If it's a cat back kit, that's when you'd have to consider upgrading or keeping your stock dp.

If its a 4" kit, its debatable to just buy a bigger dp. If you're looking at a 5" kit, then you prob want to, because you'd have the stock 3" dp opening into 5" pipe.

These are all just my personal thoughts and opinions though, I'm sure someone with some more knowledge on the subject will chime in also.

Ya if i was going to get a turbo back i no it would come with the dp. im going to order the single stack kit from FTE diesel and they have the flex pipe adapters for stock to 5inch dp. So just wanted to no if it would do me any good to change the dp would i see a big change in a aftermarket one or not..Thanks guys

From stock to a 4" DP you should see a pretty considerable drop in EGTs since there will be quite a bit of less restriction after the turbo, it also should spool a little quicker. I am thinking that when I do my injectors, I might take off the exhaust manifolds and port match, ceramic coat them, and a good cleaning of course, to spool the turbo quicker also. Just some food for thought.
