So, alot of people have been complaining that this catback may be too loud etc. At first i was nervous this was going to sound like my 2010 Camaro with the 416ci motor from what people described to turning the key and being pleasantly surprised that this isnt even remotely obnoxious. This is exactly how a truck should sound and is quiet in the cab cruising. I went from stock to the AFE catback to the Flowmaster outlaw and the Flowmaster isnt incredibly louder. that Super10 had me scared at first. Just food for thought for those that are scared of ordering this system, dont be!

Listen to the birds so you can get perspective of the volume of this exhaust. Its really not offensive at all. This is a cold start, warmed up with those 3 monster cats hot this exhaust is pretty quiet.

Immediately after I knew this exhaust system existed I wanted it for my new rally 2 that should be hear next month. How is the dreaded v4 drone in the cab. Hearing about this issue gave me second thoughts on this system and exhaust in general.

The "V4" mode drone wasn't too bad for me but I got a tuner about 2 weeks after the exhaust to get rid of it. If you have modded your truck at all the best thing you can do for your life is get rid of that "V4" crap. I know the reviews are mixed on actual gas mileage savings but for my money it's a slap in the face of America. These trucks should eat and crap out the local Prius, not run like one. :M16:

I dont have V4 mode as I was dyno tuned right after i bought the truck. I have ZERO drone with this system. You can hear the exhaust on throttle with the windows up but its very tame and not annoying.

      I prefer new, but not without a deal. Historically I've bought severely aged new inventory, leftover model year, unpopular configuration kind of stuff that sits around on dealer lots until they just want it gone. $10k off MSRP kind of stuff on a mid-priced truck. That really, really helps knock down that first year depreciation. It also requires being somewhat flexible on colors and options. I wouldn't buy a 4 cylinder if I was looking for an 8 cylinder, but if I got blue paint instead of black, or a great deal was lacking a minor option, I'm willing to overlook those things for savings.   Used <> used. Condition and history are everything. If I'm buying used I'm looking for cream of the crop. The truck from the guy who religiously pampers it, and then decides a year later he wants newer and nicer. NOT the ex-rental vehicle, or the crew cab traded in by the family with 7 kids who like to throw food, and the oil only got changed when there was time long after the oil life monitor started alerting.

      OCI, not when but why?

      @Grumpy Bear the conclusion from your post about doubling engine life has me curious. Are we literally talking an expected life of 250,000 miles potentially becomes 500,000 miles with a step up in filtration for fresh oil at "the oil factory" when it's bottled? I know you said that's a single variable among many, but, that's significant if the implication extends that far into a real world use case. I would think the oil marketing folks would really eat that up and make it known.   Particles introduced during oil change is a fairly easy one to avoid, but probably not intuitive as one would think. I.e. using a clean funnel. But...what was it wiped with? Paper towel leaves behind little fibers. A solvent if not dried is not something one would want to introduce into their engine with clean oil. And, keeping the oil filler neck clean and free of buildup.. Look at some guys engine bays and they're an absolute mess. Some say that's better than the drawbacks of cleaning it. I'm not a buyer of that idea.   I've also wondered if "flooding" the top end of the engine with oil while filling is a bad idea. During normal lubrication the oil flows in a gutter back into the galleys. But if you flood the area you're potentially washing the top of the rockers, springs, and other areas which may not get much oil wash normally, and you're mixing all that into the new oil. I just don't have the patience to pour slowly. 😆

      DTC P2C48 auxiliary cooling pump

      By Newduramaxh*ar · Posted

      It was a bad pump, i had a dealer next day the pump. Gm part #86591535. Tools needed 10mm socket, pliers for hose clamps, 1/2gal of Dexcool. About 30mins to remove and install, pump located near oil filter on driver's side frame rail. I had a local mobile mechanic delete the code, he had a snap on scan tool. My scanner could not delete the code. I drove back home about 700 miles since then, and no check engine light. Hope this helps someone in the future in the same situation i was in. Thank you to all that helped me.
