Upgraded exhaust

Thanks Stu. Did it make a difference to performance? I don't want it fully sick and noisier. It's currently running out to the back.

I changed my truck's exhaust from the standard 2 1/4" to a 3" system from the manifold, including replacing the exhaust brake. I do not know if there was any power increase, but if there was it is pretty minimal and not something that is "seat of your pants" noticeable.
I was not really upset by this, as the main reason for me changing the exhaust was so I could route it better, not to get more power.
If you have the opportunity, chuck the truck on a dyno before and after updating the exhaust and report back any differences.
The only problem with doing this is if you have a minimal increase in power you might question why you spent your hard earned on a new exhaust.
I also have a full flow muffler, and to be honest, it's not what I would call loud. Actually, unlike petrol engines, diesel engines are not normally all that loud, even without an exhaust.
A simple test would be to disconnect the exhaust flanges and remove the muffler. After doing that, take the truck for a drive and see if you notice any power difference.
That should be pretty similar to putting a 3" pipe after the exhaust brake and will cost you nothing to find out. That's assuming your muffler is positioned similarly to mine, which is pretty close to the engine/exhaust brake.

My idea is if you are going to a 3" exhaust why would you leave a restriction in the system (original exhaust brake). It will certainly help the turbo by opening it up to 3" - faster spool up. By how much only you will know after it is done. Dyno before and after would be good but that also costs dollars.

I have the 3 inch full exhaust system incl upgraded exhaust brake, if you drive mainly hills etc I found a decreased effectiveness of the exhaust brake in those situations.
