My 07 Denali XL 'build'/Check Engine Lights/Questions

thank you. the 917-107 seems like what I would need(pretty neat too!), but does not show it as fitting the 6.2 for 2007.

does not seem to be leaking from the broken bolt location however (pass side front bolt).

I did 3 of the 4 corners of my 07 6.2L 4+ yrs ago with:

anyone know of some decently priced headers/ypipe/exhaust type setup? longtube or shorties. not looking for a huge perf increase, think I need cats. I'd be ok with a y-pipe that bolts up to the factory location as well (with no cats, or high flow?).

I put that 917-107 clamp on. I need to get a new gasket to see if it actually helps. Pretty neat item!

Will headers or y pipes that fit 5.3/6.0s also fit the 6.2 or are they different?

So did you fix the stalling or did it persist?

I did fix it. Not sure if it was just the oil presure dropping too causing some kind of issue (vvt maybe??), or the TB (I gave it a thorough cleaning). Fixed a damaged pcv hose as well.

Oil pressure is still pretty low in gear with hot idle (500 ish rpm). Probably 13psi? Runs great now though. 168k now on it

Wife is wanting to use it now, so I need to actually fix it (was just using it as a back-up vehicle as we have 2 others and I have a company car). Need to fix the suspension, seats, windows, and 02s or cats.
