thinkin bout 5in turbo back good or bad? also need a fuel pump what the best? got the edge w/ attitude chip

 

I have the Flo Pro 5" exhaust and love it. Has a great rumble and no drone on the Interstate... as far as fuel pump, I'm guessing you mean lift pump. I purchased a BD lift pump about 25k miles ago and have had no problems. It is around $250

 

Really like my Flo Pro from George @ 8 Lug Truck Gear!

 

Just to throw in my $.02, I went with the MBRP Turbo back with 6 " tip. Could not have been an easier install (and I'm no mechanic). Install took about 3 hours in the driveway with a buddies help. hardest pasrt was getting off the old exhaust. Sounds good! Good luck!
