Duals for our trucks - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I bought Dynomax (coated) headers, a Hooker dual exhaust kit, an "H" pipe kit, and a few other goodies from Summit Racing. My "stuff" arrived within 2 days, the prices were very good, but the main reason for my good review of Summit: the parts man I talked to (Kevin, I believe) was very knowlegable, and helpful. I specified 16 ga steel in all items, he verified that, and helped me pick out the mufflers.
The headers "fell in" the engine compartment, didn't have to remove much, didn't have to raise the engine. Spark plug changes are a breeze with this header, and the coating looks great!
The Hooker duals fit right, and all bends are mandrell bent (zero restrictions in the bends). The dual kit came with clamps and hangers, I am very pleased with the quality of this kit! All tube ends are swaged (makes it a "driveway" bolt-in project).
To help eliminate rust in the duals (my truck is driven daily, in the "rust-belt"), I used Por-15's newish exhaust system coating. I coated inside the pipes, and outside, and coated all hangers, bolts, clamps, ect. This stuff looks good, and I will post later as to how well this coating protects against rust.
E-mail me, if I can answer any questions. steve (aka shadetree)

Randy, I dug out the invoice from Summit, the parts numbers and prices are below. I also see that the counterman who was so helpful is named Calvin, oops, my bad.
HOK_16522.......exhaust system.....$116.95
SUM_630122......perf. turbo muffler..14.75 ea

WLK_86003.......coated sbc headers..209.95
SUM_642022......2.25" balance tube...32.95

shipping was free, and incredably fast, however, I had to pay a surcharge of $8.50 for the oversized header & exhaust packages. Still, cheap, in my book.

This sounds like a great setup, I have a few questions. Where do the tailpipes exit? How does it get past the trailing arms? What size are the pipes? Thanks for any input.

The inside diameter is 2.25", from the collector all the way back. The tail pipes go over the rear axle, starting to go "up", near the swing arm pivot point. The tail pipes exit behind the rear wheels. This system is easy to install, it just clamps together, the hardest part is connecting to headers, or the stock manifolds. steve

Primer, the Dynomax's are 26" average tube length (not equal), and in my truck, the header collector doesn't hang any lower than the original exhaust pipe did. Ground clearance doesn't seem to be a problem.
