This question gets asked once a month. Personally I would just use what you want as long as it’s a 0-20 synthetic that is compatible. Except I would try to be consistent. Using a different brand every year your just mixing all these different detergents in there and who knows how that may affect wear. My old man has been using the same oil change place that his boss owns since new on his ‘07. Has 235k now, and he’s only changed oil, bulbs, and brakes. Coolant and trans have never been flushed, and he gets a clunk sometimes probably due to his broken leaf spring. It just proves that some of us care too much (myself included). I chose pennzoil because shell always has a decent rebate as I was already using shell rotella t6 in my car. I don’t drive enough and I try to change oil every 12 months or so.

The cats and front resonator really keep these trucks quiet. My corsa sport was not very loud at all in the cab....actually didn’t seem loud period. After adding catless headers I can still hear the old lady talking....unfortunately. Therefore I think cab noise will be fine with whatever cat-back you choose Edit: I forgot to mention adding headers at least doubled exhaust noise.

I just wanted to say I too used the oem 90 connector and I used a short extension harness that I cut and added about 3ft to it for my crew cab. I think I had $80 all in and had to get black bear to add e85 to the tune to read the fuel mix. Cost per mile wasn’t much better than 93 when I drove to TN but their cost difference was .80 to .90 vs $1.00 here in Ohio. My next long trip I want to experiment with E30. I calculated about half e85 and half unl 88 or 87 would be a baseline to start with. Unfortunately I don’t drive my truck enough and usually get free fuel anyway at stations not offering e85. Therefore it’ll be awhile before I can really benefit. Sent from my iPhone using Tapatalk

I left factory wires on, but my truck only had 9k on it last year when I installed the headers. Depending on miles on your truck it may be worth doing them while you’re in there. I bought 12” wires to get free shipping but just decided I’ll wait until I do plugs. Sent from my iPhone using Tapatalk

I am assuming you are referring to a swap from L83 to L86. The MIT tube is identical between L83 and L86, and yes the only difference is the silicone coupler. L83 - MIT 3.875" to 3.5" TB L86 - MIT 3.875" to 3.875" TB

TB end for L86 is 3.875” vs 3.5” on the L83...hence why the intakes have different part numbers. Sent from my iPhone using Tapatalk
