    Notes
    5" 20 degree bend off the end. Includes flanges and gaskets.
Using this kit makes the hook-up of your exhaust system a snap! The 2-1/2" diameter, 16-gauge, mandrel-bent tubes curve back at a 90° angle and are offset outward to clear the bellhousing and starter. They drop 10-1/2" from the header flange and they extend backward 17-1/2" after the 90 degree bend.

Just trim the length, weld on the 3/8" thick collector flange (included, with gaskets) and you're all set! Works great with any tight-fit headers. Header not included.

What a Great Kit!

By ChevyGuys from Phoenix, AZ on 11/29/2010
Bottom Line: Yes, I would recommend this to a friend

I bought these to go with Speedway's 2 1/2 in Ram's horns (The OEM corvette ones) The collector and downpipes for the 2 1/2 inch ram's horns are very hard to find. Sure an exhaust shop can make them for you. But this kit is cheaper than they can make them and you will benefit from the clean look and performance this kit will offer you. The only con is the flange thickness. It would be nice to see a little thicker flange provided.
