Exhaust

Hello everyone i just purchased a 2010 gmc duramax with 140,000 i went threw it with a fine tooth comb the highest injector balance rate was -.05 blew my mind away as they are still the original. The truck has duramaxtuner.com spade jack tuner with 5 position switch on it but everything else is stock was wanting some advice of the best exhaust not really wanting to delete the dpf and egr right now. the truck right now is getting a little over 15mpg town how much would i benefit from straight piping it but leaving the dpf on or should i wait an do the egr and dpf delete at the same time or just leave the truck alone.
thanks for any an all advise.

Won't make any difference if you leave the DPF.
leave it as it and drive it

Please take my advice and delete the dpf lol. You will get slightly better MPG but its will sound so much better and you wont have to worry about it throwing you into limp mode when it decides its full.

I did a turbo back 4" exhaust with the dsp5 switch but i used ppei tuning which is the best in my opinion. Dont use crappy tunes just spend the extra money and have it done right.

Yea you can leave it on. I have mine turned off but plan in having taken all the way out before too long so i don't have too worry about coolant leaking from it. But you will be fine for awhile just leaving it turned off.
