Great produce but reduces vehicle clearance on GTO.
The build quality on these and the Kooks headers I bought with them are top notch. The only issues I have with these is the cats reduce ground clearance a bit and the gaskets they come with require high-temp silicone gasket maker. The cats on the factory mids are up higher towards the manifolds but the cats on these are at the bottom along the plane of the rest of the exhaust. I've scraped a couple of driveway inlets but nothing serious. If the old gaskets aren't in decent shape, I suggest buying some new ones with the proper inner diameter to account for the larger diameter over stock before these mids arrive. Definitely happy I bought them.
