I been looking on youtube......

So any reccomendations?

I want downpipe and eveything.....IT a 97 dually truck f350, ext. cab

 

what do you do with the truck? ie, use the whole bed alot? tow a fifth wheel? haul stone?

do you want a little noise or the "hey here i come" noise?

it depends on what you do with the truck and what you want to say with it. i have run stock, 4 inch, and 5 inch in the stock routing, and 6 inch stacks.

of all the set-ups i love the stacks the best. the only drawback i have is that you lose the full 8 foot bed use. it has no effect on me but someone that hauls alot of 4x8 sheets of stuff wouldnt want stacks.

if you want to stick with a traditinal routing then i liked the 5 inch the best. no performance gains over the 4 inch that i could notice but the sounds out of the 5 inch is much deeper and throatier than the 4. and the 5 inch tail pipe looks much meaner than the 4 does. as for drone, i didnt see any difference in 4 or 5 inch. the stacks have a very light amount of drone at 1900-2000 rpm but its very suttle

 

I can't do stacks.

I want stock routing and I tow an enclosed race trailer......I want the power and hear some whistle.

 

3 inch downpipe to 5 inch exhaust. if you want lots of whistle run no muffler.

Will the turbo be that loud even with just a stock one?

I mean a stock turbo, just with the exhaust....

 

my whole engine is bone stock. i have a 1705 superchip (baby) and some homegrown resistors thrown in to boost timing and oil pressure. the fuel system and turbo is all stock.

 

Wow. I'm impressed


My first thing is going to be air intake then the ex. system after that. Once I find what I want.

 

thanks for the compliments, she's all bark, not much bite...lol will outrun a mostly stock 6.0. passed that she's just a hard pulling machine.
for the air intake do the 6637 modification, total cost should be about 40 to 50 bucks and maybe 20 minutes of your time. you need a 6637 air filter available from napa stores for around 30-40 bucks, a 45 degree 4 inch exhaust elbow, and 2 constant tension clamps.
this is your end result. (this is an old pic, i will take current ones tomarrow since i'm off work)

 

I got the info on the filter mod today. Thats going to be my first thing.

What about this kit?

mbrp has good kits, that was the 4 inch kit that was on my truck. thats not a bad price for it. all of my exhausts were run with no muffler.

 

i dont know of anyone that sells a cheap 5 inch exhaust for our trucks, what you can do is get the cheap 5 inch kit for a 99-03 truck. the only reason they wont fit our years is the downpipe. you can put the 3 inch round downpipe in instead and step up to the 5 inch pipe with only a little modifications. for my 5 inch kit i used pipe off big trucks and welded my own hangers on the pipe in the stock locations. didnt take long at all to fabricate. but if you arent interested in that then the 4 inch is still nice.

 

here is the 3 inch round downpipe to 4 inch straight exhaust on my truck.

the turbo whistle at idle is much more pronounced on hot engines, and it was much better running the 5 inch exhaust but you can still hear it on the first 4 inch video a little bit

 

I might just get the 4" for now


I can fab all the stuff up but don't want to spend too much time on it. I have a race car too and between that, work, work trailers, car trailers etc. I have more than enough work to keep up with

 

i hear that! you should be more than happy with the 4 inch system. i was for a long time until i got greedy and wanted more. the time will come!
