What should I expect from adding a profab 3" down pipe, 5" MBRP downpipe back straight exhaust? Will I loose too much back pressure? how about EGTs and power?

lower egts and more and better sound. its a forced indution motor u do not need back pressure the less back pressure the better

somewhat right.

It's a turbocharged motor, the turbo creates your back pressure, the down pipe and exhaust will just net you lower EGT's which is :thumb

I'm looking to get those EGTs way down. the truck temp spikes, not towing anything, when I hit the mountains.

so what about the AFE intercooler pipes?

No need for any backpressure after the turbo, the less the better. The DP will get rid of the wide open screech and the exhaust makes sweet, sweet music........

Don't expect anything drastic with the EGT's you may get a 50 degree drop.

I would just go with the 4' system, 5' is just to much

my truck runs cool with my setup 600 cruising , high 700's on interstate at 75mph. but i'm also in the south and it's usually hot round here.

4" or 5" it dosen't matter power wise, it will make absolutely no diffrence. They simply sound diffrent.........................thats it..........................
