I've seen alot of people running the 5" turbo back setups, I haven't heard of no problems yet.

No, it will not hurt the turbo. We sell a ton of these kits and have never ran into or heard of a single problem.

Do you guys offer a 5" system with muffler delete pipe? I am looking to get a straight pipe 5-6" set up

I assume you mean a 6" tip on a 5" pipe but that just got me thinking that I wish they made a 6" system for duramax's. That would sound awesome! Pointless, but would sound awesome. (based on the my theory and opinion that 5" sounds better than a 4", ergo, 6" would sound better than a 5".

The MBRP kits we have include a muffler. If you wanted to delete the muffler, you would also need part number MDA531. This is a straight pipe replacement for the MBRP muffler. I would get the system first though, the MBRP 5" muffler is not much of a muffler at all.

ive got the 5" MBRP, no cat or muffler. got the cat delete and muffler delete from PTP, ill agree that the muffler isnt much of one, i noticed very little difference with the straight pipe. i found it to be a huge pain to replace the muffler with the straight pipe and would suggest to do it the first time if your pretty set on that setup.

That is my plan. I want to order a 5" system with muffler delete, I dont wanna have the muffler. I want to be as loud as possible.

5" no muffler and no cat is about as loud as you are gonna get

I have talked to some people and they say that the 4in is better then the 5in they say the 4in has better performance.
