Oval exhaust cutouts solve the problem round cutouts create on a lowered car: height. The oval body sits flatter against the floor, so you keep ground clearance where a round cutout would be the lowest thing under the car and the first thing to scrape.
This collection holds the single and dual 3" stainless steel weld-in oval kits (313530 and 313530D), the replacement 313530C motor, and the oval gasket. Weld-in means the body is welded into the pipe rather than clamped over it, which is the stronger installation and the one that keeps the profile lowest.
