hey hows it going guys?well i was about to buy a MBRP 5" exhaust,though then i found out that the elbow is 4"...So it goes from a 4" to a 5" i guess..Well i was wondering if anybody makes a 5" exhaust from the TURBO BACK and a reasonable price..any help would be appreciated

The stock turbo and all aftermarket singles have a 4" outlet. The MBRP has a 5" downpipe that goes into a 4" flange.


A TRUE 5" exhaust will require a turbo with a huge exhaust housing, and it will be nothing you can light by itself.

ooo and also i have a early 04!!well Browns Diesel is going to do the truck!!though i just wanna know if any manufacturer's make a 5" true exhaust..im going to go with a 64mm turbo and i just wanna start buying the parts so i can just send it off for the labor..Brown can make a Bracket/elbow/downpipe 5",though im just checking if i can find one already made

shopdiesel is the best ive found. $310 shipped to your door. as mentioned the turbo is 4", but with the shop diesel kit, it immediately goes to 5"...top notch system thats cheap IMO

fordassassin

yes i know that the turbo outlet is 4",though im looking for a downpipe as well that is 5"!!i looked and the SHOPDIESEL exhaust has a 4" downpipe

I believe 04.5s have a 4.5" downpipe that will bolt right up out the 04 down pipe.

Since you have an early 04 you will need an HX-40 downpipe for the new turbo, the turbo back kits you buy will be for the stock turbo flange. I would buy a 5" cat-back exhaust system, a short peice of 5" pipe and a 5" hx-40 downpipe, that will save you some money.

I believe 700rwhp has been done with 4" exhaust...

a 4" downpipe is fine

Almost 900 hp has been don with 4". It doesn't make any performance changes compared to straight 4" until 650 rwhp. Even then it is only a couple of HP.

As mentioned above, get the 04.5 elbow.

The 5" systems for the 04.5 are just 4" right off the elbow and quickly neck up to 5". That is as close as you are going to get.

I have the 04.5 elbow sitting in the garage waiting for an 04.5 exhaust. You need the clamp too!

Even if you use a 4" system its nice to have 4" elbow instead of 3.5"

Not the one thats on my truck, its a 5" down pipe.


As mentioned the 5" isnt worth it as far as hp goes. I did mine for the tone and would do it agian, it does sound much better imo.

How much does a 5in help with EGT's compared to a 4in?

Erick Brown,what size exhaust does Richard have on the single cab?im guessing its the 5",what did he do at the elbow?i remember he was telling he has a bracket that makes it 5" right from the Turbo back!!and yes i want the 5" because of the TONE and i heard it helps EGT's a bit

Reb.B

you don't need 5" for what you are doing. My reg cab has 4" downpipe. You have a lot to do before you need to worry about needing larger than 4" downpipe. Main thing is not to get excited. We need to see what turbo is going on, then get the 4" elbow if needed and get 04.5 exhaust then. If you buy a 5" exhaust for an 03-04 then you will be worse because of the small elbow.
