Query: Great product

I installed this on my 98 GMC K1500 x cab stepside with the full cat back Magnaflow exhaust system. The hook up is same as stock except the entire system is stainless steel which is great for long life. It was also installed with a set of JBA headers. All of the flanges are nice and thick and do not distort when you properly tighten up the mounting hardware. I did have too obtain stainless hardware for this from an outside source and not the typical hardware store stuff, all aircraft grade for long life and higher strength. I highly recommend this product.
