THE Remflex gasket I purchased for my Oldsmobile has greatly improved the performance of my exhaust system. As a result of using this product, i found that the engine was running smoother and with less noise. The gasket is well-made and durable and has held up to the everyday wear and tear of my automotive hobby.The only downside? It's a bit pricey compared to other gaskets on the market, but the quality and performance make it worth the investment. Overall, I highly recommend this product to any automotive enthusiast in need of a reliable gasket!
