    Corvette Side Pipes & Headers

    Doug's Headers Sidemount headers deliver the most aggressive style and performance for your Corvette. Doug's Sidemount headers are mandrel bent and manufactured from 16-gauge tubing for a super hi-flowing exhaust system that not only looks great but sounds great too.

  • Thick Flanges Prevent Warping
  • Stitch-Welded Ports for Added Strength
  • Machined Sealing Bead Eliminates Leaks
  • Heavy-Gauge Tubing for Longer Life
  • Precision-Formed Collectors Reduce Back Pressure
  • CNC Mandrel-Bent Tubing Provides Accurate Fit & Better Flow

  • D952 - Doug's Corvette Sidemount Header Systems is rated 4.0 out of 5 by 3.
    Rated 4 out of 5 by from Great fit and quality Love fit and quality compared to another brand header I was using. That said this is not what I'd call an easy install on a C3 corvette as getting the rocker panel off if not probably going to be easy due to corrosion. Fasteners will probably have to be drilled out and remediated. Further more the muffler inserts I got required about an hours of "adjustment" to fit inside the pipes. Also upset that some people will need to grind/modify fender and rocker panel for fitiment that is NOT mentioned anywhere until you get install installation instructions with the product. I did not modify rocker panel. Overall great product but publishing install instructions online, being more clear in description that some body mods may be required and better muffler fitiment would give it 5 stars.

    Rated 4 out of 5 by from good product These were used with a Dougs header and side pipes on a small block Corvette. They sound great. Installing them was difficult and required grinding and brute force to get them inserted.

    Rated 4 out of 5 by from Great sound They did not just "slip" in but and to be "persuaded" to fit. Several busted knuckles later and they are in.
