will aftermarket exhaust cause problems?

[05f250inmn]

I want to keep my truck mostly stock because of all the horror stories I have read about modding the 6.0. But I would like a little more sound from my truck without causing problems. Thinking about turbo back systems what would be best?

A free flowing exhaust is a great thing to do and will cause NO problems at all. Anyone who says so is
Also, if you've heard "horror stories" about modded 6.0s, you're talking to the wrong ppl. Stock is not as reliable as modified ones. Even with religious maintenance.

What he said ^^^. Get yourself a monitor and make sure your truck is healthy!

have a insight and all my coolers and egr, HG's were replaced about 400 miles ago (by the dealer before I bought it) Wish I would have seen the truck before they started fixing it I would have had them put arp's in

I have almost 190,000 miles on my truck with stock bolts and gaskets. (knock on wood)

your best bet is to listen to exhaust clips on youtube and see what you like personally, I had the MBRP duals to start, which was loud, then went to straight pipe 4" turbo back and was just obnoxious, this time I think I am going with a silver line muffler/ NO cat system.

I've been running 4" TB straight piped duals for 4 years. Never get tired of listening to it.

Putting a good custom SCT tune on your truck will really wake it up and not hurt reliability. Since the head gaskets were done so recently you could swap the head bolts for ARP studs one at a time without taking the heads up if you wanted to. But if you keep the hp to around 400 or so your head bolts will be fine.

Don't hear guys mentioning it, I'd retorque them after a couple heat cycles.

You don't hear it mentioned because it is not done. The head bolts are TTY (torque to yield) and are not tightened to a torque spec. They are tightened to a certain torque and then given another 3/4 turn, stretching the bolt to its yield point. That is why the head bolts must be replaced every time and are not reusable. They can not be re-torqued.

To retorque the new head studs that is, not reusing old ones.

Reason I mentioned is a couple months back a friend with 6.4 had his head studs replaced and a short while later he started to have oil leaks. I asked if he retorqued them and he said the same what you said "never heard anyone doing that"

My comment was from years of building 2.0 big tubo engines, we always retorque them after a few heat cycles to prevent blown heads, leaks etc.
