I am not to worried bout my setup.
I worrie about my turbo. I don't know how much "play" is acceptibal in the wheel. Probably should rebuild it with some new bushings.

But, going to stage 1's and a chip here.
I have 3 inch dp and 3367.
I'm sure I'll be fine. I've never heard any wierd noises slowing down. All I can hear are my injectors rattling. haha.

tatsch what is the best way to check my turbo for bearing failure so i can check it from time to time and take preventative measures before this does happen? i been planning on pulling the cat out and putting a piece of pipe in its place. would you suggest flex or hard pipe? cause i can get thin wall electrical conduit same size as exhaust for free to weld in there. kitty is gonna say bye bye asap. ain't no use in puttin it back in. no emissions checks for a good 90 mile radius around where i live

on the exhaust i would go actual exhaust pipe over flex. just cut the factory flange that bolts to the downpipe off the cat and weld it onto whatever you decide to use in there so you can still unbolt the dp. if you can replace the dp do so, but i'm just saying i didn't and didn't notice any harmful noises, turbo stall, or anything like that. just the egts got hot quicker

Here is a good article on why moving air not only in the engine but also out of the engine is equally important. It's for gas engines however it also pertains to diesels. Easy reading and quite informative, I thought.

Thanks for the article Jim.

Just remember with a gasser, back pressure is important.
with a diesel, back pressure is bad.
Thats why the DP needs to be replaced. To much backpressure for performance. For everyday grandpa driving, its fine.
