I am getting a 4" exhaust turbo back to bypass the DPF and Cat to increase performance and sound. My question is should I go with a straight pipe or should i get the straight pipe that turns into the dual exhaust?

I plan on putting on a black Maxx tuner along with the egr delete and cooler delete.

Do i need to put a muffler on it? I just don't know if a straight pipe with no dpf,cat or muffler would be too loud.

Any suggestions would be great thanks a lot in advance!

f250 6.0l no mods just purchased, running on 20's.

 

If your truck is a 6.0 it does not have a DPF. 4" Turbo Back will work just fine.

You will like a 4 inch. May even pick up a mile or 2 in mpg. The downpipe on those is the hardest part. Last 2 I did for some reason I had to cut a bit of the padding around the cab to get them in. It's a tight fit but the rest is down hill from there. I'd suggest tourching the double hanger above the muffler. Lube the hangers up good for a day or 2 with some good penetrating oil prior to the instal. Try and save those hangers and a sawzall is your friend just cut the pipe. I'd recommend going with stainless steal. Or vendors can help you with your purchase I like magnaflow myself.

 

What do you think about a 5" and I shouldnt need a new manifold right? Should bolt straight to the turbo?

 

5" will give a little deeper sound.

I should be good with no muffler on the 6.0 correct?

Anyone have any ideas about the need for a new manifold or if I need a muffler on my truck?

send bigrigs a pm on here he has diamond eye 4in duals with there race muffler and it sounds really good. i would deff. put a muffler on it. bigrigs ran straight pipe for a bit with his duals and it sounded good at low rpms but up top it was very raspy and loud. now with the muffler it carries a nice tone thru the rpm range.

 

I have a 2005 F-250 that recently had a rough idle, slow take offs, engine shuts off when i came to a stop, but now its running great for some reason. Now the truck is running great but i have white smoke blowing from the exhaust and its using coolant. I ordered a bullet prood oil cooler and egr cooler. I was wondering if im heading in the right direction any info??

 

Scarecrow thanks for the grear info. Wes could you post somewhere else instead of trying to highjack my thread? Thanks
