I clearly am mistaken, pro-fab gets my dollar.

Dmax store on top
PPE
Pro fab on bottom

When I put manifolds & up pipes on years ago I thought the turbo spooled alot quicker almost to the point of eliminating the lag

I dunno. Each truck I've rode in that had them put on did not come on boost as fast as it did before. That was two different stock fuel stock turbo trucks that were not running max effort tuning (that is the key part in my theory). Maybe it's just me. Dyno run with before and after with different tunes used would answer that in a heart beat though

OK go for it and say I'm nuts, I don't deny it in some aspects of my life, but, I did this fender cutout a long time ago on my LBZ and turbo did spool much quicker. NOTE:, I did not do the PPE mod to the stock airbox.

I also gutted the IAH to keep it emissions looking friendly, added a 3" hotside pipe and insulated it, 3" Mishimoto coldside fittings (found them on craigslist for $100.00) and I would have to spend the additional $100.00 for the uppipes with the EGR riser as that is the first thing the emissions "techs" look for during the underhood visual emissions inspection.

I would not install the uppipes until I had a LLY turbocharger ported and polished and minor upgrades on both wheels.

As it is right now I have to be careful and watch the 4-5, 5-6 upshifts so WOT rarely happens with what few changes I have made. It's OK as locking it 4th gear brings it up to 80-90 mph pretty quick. If I'm not careful with my right foot the upgrades that I have now would send me packing to Disneyland for a transmission rebuild sooner than later, BTW, I'am accepting donations...

Everytime you change something on one side it has an effect on the other and overall I have not spent too much money on upgrades since 2013...

For when or if I ever did the LLY turbo upgrade the exhaust manifolds were ported and polished to match the uppipes as opposed to the expense of cast headers....

My EGT's like Russel said in this post drop like rock when letting off the throttle..

I thought the PPE's were ricks but rebranded and coated? Whereas the dmaxstore appears to be more along the lines of a straight copycat. Rick?

Mike I had almost bought the coldside mishi fitting off the intercooler to feed the race pipe. My main like of them was that they are metal with band clamps vs plastic with qd's. Figured it would hold up better. Worth it?

Mishi said they'd sell the one fitting for $80, then you'd need a 3-2.5" 5" boot for the race pipe. PPE made a boot for it, but I left my coldside off the cooler stock for now since i'll probably do a cooler prior to turbo anyway

They used to be, but PPE decided to save some money and start making their own. It looks like they sold them to DmaxStore to rebrand as their own (like Rick used to allow PPE to do) because they look exactly the same.

They must have changed their policy. I contacted them a couple of years ago asking about this, and they said they would not sell pieces individually.

What ever ones you get i'd recommend getting them coated. When I bought mine over 5 years ago they where coated by calico coatings, they still look good.

Roger on PPE/Dmaxstore. wasn't aware PPE started making them in house.

Im not sure as far as Mishi. I called them up a few times asking about that kit, I think $300 is insane for what you get, I explained I only needed the one piece, they said no problem after taking a few days to isolate the part number. I thought at the time that it is cool, but not worth the $80 or time to install as a standalone, but a good addition when an intercooler is added

Cerakote won't give you the same thermal barrier that ceramic coating will give you and that's the whole purpose of coating to seal in the exhaust and send it to the turbo and not disapate through the manifold into the engine bay. I had mine ceramic coated and then used heat wrap.

Not to argue, but cerakote is ceramic.

http://www.cerakotehightemp.com/reso...VelvetTest.pdf FWIW.

Since you can also buy and use them raw, the coating for me is for rust prevention as I live in the norhteast on the water, where we have salt 24/7/365. Ricks coatings are specifically mentioned to do nothing for rust prevention.
