4" exhaust

[McChicken]

I have an 08 250 with a 210 spartan tune and I want a 4" exhaust. I was just wondering which ones you guys prefer.

We have had great luck with the Flo-Pro and AFE kits. Diamond Eye just released theirs and MBRP will be coming out shortly as well.

I have the Banks exhaust on mine, the install is very clean and the dual tips look very cool.

I have deleted the dpf and I am wanting to run a 4" straight back with a 5" tip. I don't want any cats or muffler. What about the H&S kit, will it work with the spartan or just a H&S tuner? And whats the deal with bungs? Go with them or without them?

Any exhaust will work with any tuner per say.
Now H&S and the newer Spartan you can get the exhaust without the bungs for the sensors.

I've been reading on some other post, and would it be better to run a 5" exhaust with a muffle so it will be cooler of does it matter? Which 5" do you get the best performance out of?

4in will outperform the 5in unless your pushing larger HP numbers. On a stock or mildly tuned truck, the only thing a 5in will do is get you a deeper sounding exhaust note.
