Bigger than 3.5 inch down pipe?

[T.R.P.]

When I went to look for exhaust systems for my truck, I was told that the down pipe in mine (06, 6.0) cannot be bigger than 3.5 inches.

I want the mbrp turbo back 4 inch. How can I get a 4 inch downpipe in there?


Also, I hear alot about people getting SCT's with tunes. I don't understand what this means?

I have a super chip, plug it in, tune it and go.
What is the difference?

I think the SCT works the same as your superchips, but the SCT can hold custom tunes on it.
Custom tunes are designed for your truck and your mods......not just over the counter sell to everybody tunes like the other mass produced tuners available.

Well, what I'll probably end up doing is the exhaust, chip, and air filter and thats it.

I have 35 inch tires though and may put a 4.10 in the rear end eventually.

What kind of difference are we talkin here?

I think they take into account your gears and tires as well as exhaust, intake.
I have not ordered them yet this is just the way I understand it from other threads I have read.

Lets say I get the exhaust, and a bully dog power pup, along with my air filter, how critical will it be to get apr studs and an egr delete kit? From what I've read, those two are VERY expensive. I am only 16, you see, therefore, I cannot afford some things.

That would depend on how you were going to drive it.

TRP save your money! You dont need an air filter. Stock flows enough and filters as good up to the 450-500 mark if I heard right. I have heard people buy bully dog, edge, and others and the only advantage is shift on the fly. Get an sct. It can If your worried about studs get custom tunes from Cale from Brians Truck Stop. I spent some time talking to him and he explained timing to me some and I have recently ordered 3 of his tunes. I believe his tunes will be easier on stock bolts. Another Great tuner is Eric from Innovative. I have been running his stuff for about 10k miles. They tune different and both are super guys to work with and get you what you want. As far as your exhaust, I run a 4" dp and it is a tight fit but with time and a 2x4 and a hammer it can be persuaded to fit. I dont know which vendor to recommend for that.

You can run a 4" down pipe on your truck. It is tight and you have to fiddle with it to make sure it isn't contacting anything or it'll vibrate and rattle and drive you nuts. Magnaflow has a 4" down pipe with their system.

You really do not need a 4inch downpipe anyways unless you putting out some serious power.
