My 6.4 plan - looking for advice / input

[Bigshow]

Hi guys, I am new to this site. I joined here because there appears to be more performance discussion (and thus experience and expertise) than on a few sites I was on.
I have a 2008 6.4 and here is what I am leaning towards. I use my truck lots for work and am not a real high performance fan mainly because I cant push parameters too far to hamper reliability and cost me $$$. This isnt mean to be taken the wrong way by the people who love the BIG POWER applications, but rather, to garner better info from the site on my intended use. Any input is greatly appreciated...

Tuner - I have been following this for a long time, and have decided on H&S w/TPMS adjust. Im not sure if H&S tunes w/shift on the fly or KEM tuning. I wont go to any power level above the 210 range that was on the Spartan as my daily driver - a mid tune for light tow - and a lower power setting for heavy towing.

Intake - I was going to do the air box mod to reduce restriction and use a hi-flow AFE filter. If advice is NO, then will go with S&B CAI.

Exhaust - I want a DPF/DOC delete but leave stock downpipe in place. I also want dual tailpipes with exits both sides (not like the Magnaflow with both on same side). The MBRP Cool Duals look good, as does the Banks. I dont care for the systems that have a bad tailpipe angle that looks like a DMax. I would like to do something to kill the leaf blower sound - read that a MBRP rep posted that their muffler can be put in backwards to accomplish this.

I almost feel guilty for the long post, but did so to get better replies about my particular goals - thanks!

I put on my Black Maxx yesterday and love it! The gauges are an amazing asset to this vehicle as well as the removal of the danged DPF and CAT. I did these mods strictly to let my truck breathe and improve reliability and longevity..

The H&S is shift on the fly tuning right out of the box, load the tune and then you can switch back and forth between no power, mild wild, hot......I am not sure about KEM tunes, maybe someone can chime in.

Check out my thread on the airbox mod I did with my truck. I saved a lot of money buying an aFe OEM replacement filter over a full CAI. I did all my mods for the improved reliability and not for being hard on it with high tunes.

I cant say much about MBRP, as I invested in the Diamond Eye 4" downpipe back exhaust. I chose this one because of it being a relatively inexpensive exhaust, yet still retain good fit and finish. I also heard good things about it on here. I must say though, I had MBRP on a previous truck and loved what they put out. I would say you need to look up Performance Truck Products, they will treat you great in every aspect, top notch provider! Dont worry about the long post I understand your concern and was in the exact same situation as you.....

I also want more power and some sound, w/o the EGR letting exhaust gases into the engine and all the regens.

KEM tunes are not shift on the fly compatible; however, they have a great reputation for excellent custom tunes for the 6.4. I am not sure if this is an issue to be concerned about at the milder power levels I am interested in or just at the big number tunes?

Check out my thread on the airbox mod I did with my truck. I saved a lot of money buying an aFe OEM replacement filter over a full CAI.

There is another thread somewhere about another mod where they remove some baffle between the intake and the air box for increased flow as well.

Tuner- Go with the H&S Performance Mini Maxx and dont look back. It is the best overall tuner on the market. I suggest sticking with the tunes that come on the unit, you will be very happy with them. You can also play around with the other tunes available for free on the H&S website if youd like.

Intake- I suggest going with an AFE or S&B intake and being done with it. They both make high quality units that will outflow the factory box and not break the bank.

Exhaust- If you want duals, I would go with a down-pipe back Flo-Pro kit w/ muffler. This will offer a much cleaner and seamless install than getting a DPF/Cat delete and DPF back kit separately.

Let us know if we can help with anything or if youd like a quote on a package deal.

Is the adjustable TPMS working well? After watching that damn orange light for so long, would be nice to have use of the system by having adjustable parameters...

I have come to the same conclusion - Is the S&B quieter in the cab? I tow lots and dont like too much noise when working because it becomes annoying after a long day, but yet, not too old to like the noise when playing!

I havent seen too many of these down pipe systems on websites - they usually have the 'delete' stuff separately (we know the reason for that)

How would you describe the sound of the flopro muffler? I am in the minority I think, but I dont like the leaf blower sound (want a deep rumble like a big block muscle car), and dont like single tailpipes(I know some guys go this route because of $$, but I prefer the symmetrical look of duals!!).

Let us know if we can help with anything or if youd like a quote on a package deal.

Thanks - You have a good reputation from my reading...

Yes, it is, but the TPMS functionality is an extra add-on (part number 709913).

The S&B intake is quieter in the cab than the standard AFE Stage II kits since the S&B intakes are almost fully enclosed. The new 75-5054 S&B has a removable front panel as well if you need extra air flow.

We have several of the down pipe back kits on our site. In order to get duals with a muffler though, you will have to add the muffler separately. The muffler will help get rid of the turbo sound if thats what you are after.

Thanks for the quick reply -I will do some exhaust reading this evening. I saw that the TPMS module was another $100 or so - would actually like the system if the alarm pressures were at meaningful levels!
I think the S&B is the one for me - how hard is it to remove that cover, is it something that could go on/off? Could leave it on for work, but off when I wanted some howl?
Is there much of an exhaust rumble left with the muffler installed? Are there other mufflers like the MBRP, Magnaflow, or Banks that would achieve my goals better to reduce wind noise yet have a rumble? I had read about the MBRP muffler going in backwards to do this...

[DSTRBD]

The plastic cover on the S&B is easy to remove with a screwdriver. The plate I was talking about is rubber and can be pulled in just a few seconds. Below is a few pics of it.

Bump for PTP! I am semi-new as well and I took it all in and pulled the trigger on distrbd's advice and couldn't be happier. I have the 5" diamond eye down pipe back kit and it fits great and affordable. I'm no expert wrench and I installed it in about 1 1/2 hours in my driveway. Also running the mini maxx on the hot damn tunes. Amazing power and extremely user friendly. I also use my truck every day for work. The shift on the fly allows me to do anything at any time. A quick button push on the highway and I can blow the doors off the annoying rice burners. Then bump down a notch and hook up to my trailer and tow all day long.
I should be ordering my s&b and egr delete this week if all goes well! Best of luck to ya, can't go wrong with PTP!

So with these trucks drawing hot air from the engine compartment with the aftermarket kits, are they really just higher flowing boxes rather than 'COLD' air intakes?
