    Don't forget to clean those tips fellas!

    Over the break I used the "Barkeeper's Friend" soft cleaner gel on my other car's stainless exhaust tip. So, I figured why not also do the Yukon's tip too. Turned out great! P.S. this stuff is also fantastic for cleaning your kitchen sink if you've never used :)

    Where to sell OEM 2023 Suburban 6.2 Exhaust System ?

    Hey guys I’ve recently swapped out my stock exhaust system on the 23 6.2 burban with a Corsa Performance exhaust system. Now I’m tryna figure out where to sell the OEM exhaust system. Tried ebay but I have a limit on the amount since I haven’t sold anything on there. Any thoughts ?

    2005 Tahoe Ticking

    Hello, just tonight while taking pictures of my Tahoe I noticed this ticking it's making. It's worrying me a bit, but I don't think it's rod knock at all. It almost sounds like it could be an exhaust manifold leak, or at worst a lifter problem. The sound is only heard at idle and as soon as I...

    Exhaust

    Hello, I am currently fabricating a cheap exhaust for my 05 Tahoe, just a quick question about sizing. If I have a 2.5"id, would a 2.75"id connector fit over that without being super loose? What I'm thinking is since 2.5"id fits over a 2.5"od pipe, wouldn't that make it bigger and a very similar...
