Buyer’s Cheat Sheet

What to check before you click ‘Add to Cart.’

Many users prefer local muffler shops for repairs

“Super nice and helpful. Really dirty waiting room but hey you get what you pay for lol”➕

“They fixed it for $12.”➕

“I need them to be immaculate, I need them to work, and I think it's insane to pay dealership level prices on an old car.”➕

Discussion on the importance of following manufacturer's instructions for oil mixtures

“Catalytic converters don't cause problems until they're old or the operator can't follow simple instructions, if the manufacturer says use this oil at 50:1, the the recommended oil at 50:1 don't listen to the various "experts" that tell you to run it at 40:1 or any other guessed at "better" ratio, more oil means the saw runs hotter because it is running weak, but with a cat the excess oil fouls the cat.”➕
